Connecting To L2TP VPN Crashes The Phone - Samsung Galaxy A50 Questions & Answers

My phone reboots itself right after establishing a connection to my L2TP VPN server. Does anybody have the same problem?
Additional info:
SoftEther VPN server
Protocol: L2TP/IPSec PSK
Connecting using IP address and domain does not make a difference.

I've already submitted two error reports with logs to Samsung via the Samsung Members app. Hopefully, they will fix this soon.
Perhaps you can also lodge an error report this way so more people can get their attention on this issue.

Me too. I bought a phone for works. But its so sh*t. I reported the log to SS for check and fix, but dont know how long I have to wait, they dont give me a deadline.

This device is actual sh*t bro.

I tried 1st release of firmware, France, Singapore, India, Vietnam firmwares but it have same bug

Got a new OTA update today. Connecting to L2TP now crashes the phone INSTANTLY
This is bull****. Why bother promoting Samsung Knox and all these fancy TPM when the simple functionality of connecting to a VPN can't even be done?

My phone crashes after exactly 60 seconds after connected. SS didnt give me the direct contact of their technician, I can only talk to the telephone supporter, they dont know anything.

The latest firmware (May Security Patch) fixed the vpn.

Thank you for informing. Can confirm that it works now.

Yep it works. Only bug I see is that there's no white text showing when entering the text fields in a VPN Profile with the Night mode on.
Set phone to Night mode, go to VPN and Add a profile. You can't see what you type. White theme is fine. If anyone has any contacts, report that to Samsung please.

Is the L2TP/IPSEC PSK VPN connection working for some of you?
I have tested two A50'S (A505W) and they both reboot 60 seconds after the connection is established. Latest update is February 1, 2020.
Connection is created and seems fully functional (as much as I can test in 60 seconds) until phone reboots.
I am connecting to a Ubiquity Edgerouter ER-6P. iThings and Windows 10 clients are connecting fine.
I have sent crash reports in to Samsung and communicated with support staff. I haven't been able to communicate with anyone able to say they use L2TP/IPSEC PSK connections successfully.
Seeing this thread gives me hope it can be made to work.
Any tips on getting the A50 to keep the VPN connection would be greatly appreciated.
Thanks

Just connected (and browsed web a bit) to a Ubiquiti ERPro-8, L2TP, no reboots. Update is the februar 2020 one.
Are you perhaps running 2.x firmware on Edgerouters? I've been avoiding it, since they have up to 15% performance degradation and other bugs. The ER I connected to was on 1.x.

I just recieved my HTC P3300 yesterday
and the thing DOESNT go online
its connected to my home wifi network yet when I use Pocket IE it simply says "Cannot connect with current connection settings. To change your connection settings, tap Settings."
WTF?
Can I not use wifi on this smartphone? What am I doing wrong, and please feel free to flame me, I'm new to all this so I really need helpful opinions.

Hi,
If you tried to connect with your router, do you used the same script (WPA, ...) for this? Do you entered the password for your WiFi-network? Please let us know, what you´ve done to get access via WiFi.
There was WPA-PSK encryption on my network at first. Then I removed it, connected to the network again, still gave me the same error.

WM6 Live Messenger not using wifi

Hi,
Can anyone help me, this is doing my head in! When I am connected to wifi I can browse the internet with IE but as soon as I try and sign in with messenger it tries to connect over gprs.
If i delete all my gprs settings and just have a wifi connection live failes to connect at all.
Any ideas?
Cheers
Yes there is a solution to your problem and its quite simple.
Don't use WML.
This has been a long standing bug with live messenger and Microsoft has not fixed it.
I suggest you use the older and more convenient Pocket Messenger which does not have this issue.
Up to you!
I belive the issue is fixed in .2600 build. At least mine works just fine, while .1100 build was insisting on using GPRS connection.

Your are right, it also let you choose if you want to sync your MSN contact with your phone contact.
This new build correct most of the flaw of the previous one
Thank you!!!!!!!!
easy 2 fix.
disable your phone, connect wifi, connect messenger over wifi, then re-enable the phone.
should continue to use the wifi....
but as soon as you go out of wifi range, or disable itwill want to use gprs/3g. so sign out 1st.
By the way, I'm looking for build .2600 CAB and I cannot find one. I would appreciate if someone could send me a download link.
Thanks.

[Q] Wi-Fi Connection Issue?

Okay, so this is a really weird issue that I found out with my HTC Tilt2 while it was running Android, and I have a feeling it might have something to do with the WEP code (Even though I've tried it 20+ times...)
Anyways, whenever I try to connect to my home network on Android, it always goes through the same process of *Connecting...* *Sending...* *Connecting...* *Disconnected*, as if it just pings the router to check for a connection, then disables itself. Whenever I try it anywhere else however, I do not get this issue. I haven't found another location with another WEP key to try and see if its just that part of it that is unstable, but it's just a thesis. It's either that or my network, which, at this point, I wouldn't doubt if it was.
So... Anyone else getting or had this issue and solved it? Of connecting to a Wi-Fi network with a WEP key and getting *Connecting...* *Sending...* *Connecting...* *Disconnected*?
Edit: I did a bit more research and discovered that WEP is the only thing that doesn't work. Anybody got a reason other than it just doesn't work? Maybe something to do with the kernel or...?
WEP is an extremely insecure (unsecure?) protocol. Even if XDAndroid did support it, why would you want to use it? WPA/WPA2 are much, MUCH more secure and harder to crack than WEP is - with simple packet injection software, any 13 year old script kiddie can pop open your wifi.
I guess it is better than no security whatsoever if you are concerned about AP pirates, but not much. Every device in the last 5 years I'd say should support WPA/WPA2. So don't worry about WEP not being supported, it's horrid!
I think it is a kernel issue, but I don't see that being a priority for the devs to fix.

I looked into that a bit and just decided to upgrade my WEP to a WPA connection. Don't think my parents or brother we're too happy about me doing it, but from what you've said, it should be a lot better for both me and them.

Yep, and now I kind of understand why WPA is better than WEP. If you can figure out the paraphrase code behind it, then it's all easy to decode and translate and get someone's WEP code. Plus, it's a open encryption (which I think you already stated)
The more you know XD

It's on your router. You change the security setting on your wireless settings from WEP to WPA. Then any PC/device that connects to your router wirelessly will have to type in the code again.
Could you elaborate more by "it's on your router" do you mean going to the actual model numbers router and connection to it? or can it be done through internet configuration on the computer

You have a wireless router correct? There's a configuration page on that router where you secure it with a password - is this not familiar to you? Router's don't ship with wifi secured, you have to put the password on the router...
There's a configuration page you need to go to figure it out. You can put your make/model router in portforward.com to see the steps to get into your particular router.
Thank you for the help, i have now changed the password and switch from WEP

[Q] How to bypass Vodafone Romania block of Viber application?

Hello.
I'm from Romania and i'm a subscriber of Vodafone Romania.
Viber works fine on my phone on every wifi I connected to, but when I activate the Mobile Internet it says that it is "currently unavailable and/or blocked". It seems that VIBER is blocked by Vodafone Romania and the only way I can use it with their Mobile Internet Service is to pay a tax of 3.13 Euros (3.8 dollars). In my opinion the fee for this service is abuzive and restrains the rights of its users.
From what I know Viber uses certain ports so it can make those VOIP calls and those are blocked by Vodafone.
My question is simple and I hope that some users from Romania and from other countries that are on Vodafone and have their Viber blocked can help with some tips and tricks on how to bypass the block.
Please refrain from answering to the question above with answers like "Change your carrier", "Use other VOIP apps instead", etc.
Let's hope we can find a way to deal with this problem,
Thank you.
SSH tunnel
My carrier also blocks VOIP like Skype & others, and the only real way I've found to get around this is to tunnel the traffic through a VPN or an SSH tunnel.
Personally I'm using the SSHTunnel app to do this. Basically you set it up to connect to a server where you have a shell account. The app then allows you to select the apps you want to tunnel their traffic.
Of course the SSH daemon on the server needs to allow forwarding of traffic and you need a good connection on both your phone & on the server end for this to work properly without call quality degradation.
Thanks for the reply, Gunthy` but unfortunately I don't own a server and I think it would cost more to buy one then to pay for the fee that Vodafone charges.

Yeah you're right there, although a good VPS doesn't have to cost a lot more than that. Also you can do more than just tunneling with something like that of course, so you get more value for your money.
If you have a good internet connection at home you could also use your own PC to set up the tunnel, you don't need to invest in renting a machine. Mind telling me what provider & plan you're on for your home connection? I'm quite familiar with Romanian providers so I could tell you if your current plan will allow that. Basically it mostly will depend on your upload speed. Naturally your PC needs to be up to the task as well...
Well i have dual-care 2Ghz Windows 7 laptop at home and a 11MB/s download and 1MB/s upload connection from RDS.
Do you know how could i configure my computer tu use it as you said?

Both your PC & your connection seem largely sufficient to do this. How exactly to set it up on Windows is something I'm not sure about (always done this with Linux ), but there is a an OpenSSH build for Windows, so you should be able to use that. Make sure you turn on port forwarding in the settings of the daemon, and forward the incoming SSH port on your router. SSH defaults to 22, but RDS might block that, so up it to something above port 1024 and it should work. Check out this guide, it seems pretty complete on first glance .
Thanks for the useful info. I think it's a good ideea to use your personal computer in order to bypass the block. I will try this tomorrow and report back here on how it goes.
In the meantime, if someone else has some other tips please post them here.
Viber
Hi,
This is a member of the Viber R&D Team!
We have received various similar complaints from Viber users in your area of the world, and we have investigated this issue. It seems that the outgoing access to Viber and VoIP applications may have been blocked by your specific service provider [generally, this block is only on basic package plans].
Please check with your carrier, Viber will not be able to bypass your carrier's network blockage. It is in your carrier’s or country's decision which applications they wish to allow or block network connections to.
If you have any question about Viber - please feel free to ask.

Thank you for the answer and sorry for the very late answer.
Unfortunately the carrier (Vodafone) still doesn't want to open the ports for Viber, so I decided to ask for help from our national Consumer Protection Agency, because when I signed the contract with Vodafone they didn't tell me that the internet option I choosed doesn't offer me full access to the internet because some ports are blocked and I will need to pay extra if I would want to use them.
I wil update this thread when i have some moar news.
Oh, and if anybody has other ideas on how to bypass blocks like this please post them here.
Thank you.
@Vladuu -
It is our pleasure to be here and assist.
We'll be waiting for news from you, and we hope those will be good news
How about using Tor, if a shell account is not available, nor a private ssh server?

well? does it work? Vodafone Spain here, same issue...
Hi,
As far as we know, Vodafone Spain still blocks VoIP services (including Viber) on its 'simple' data plan (for users who haven't purchased VoIP access).
We assume this can be confirmed with the company itself, by contacting their customer support or checking out their mobile data plans online.

Vladuu, did you ever find an answer to this? It seems it's an intermittent block for me. Sometimes it works, sometimes no.
I droped my Vodafone contract because they were the first company to implement a voip net blockage in germany.
I can only recommend to do this. Bypassing a blockage might be against your contract, which means you're asking for ways to break your contract / the law....
I'm now using O2 / Germany. They've posted on twitter that they won't block voip, ever. You are able to vote with your money, do it!
I know it's months after the previous replies, but I also faced this problem (for Skype) and fixed it.
The solution is using a VPN, but you don't necessarily need one at home. I use OpenVPN Connect from Play Store and vpnbook.com.
Install OpenVPN, install the certificates from vpnbook.com (server1 & server2, I just just UDP, 25000), then anytime you need to use SKype, follow these steps:
1. Open you browser of choice, go to vpnbook.com, the OpenVPN tab, get the current password (they change once per day)
1a. Close the browser from the recent tasks window, or (in case you use FF) you will not be able to browse using it after you start the VPN Connection
2. OpenVPN Connect, enter the password you found in step 1. Click Connect, check "I trust this ... <>" and OK.
3. Start Skype/Viber/whatever.
Thank you and sorry for the bump.

[Q] How to connect to hidden WiFi?

Hello xda community!
I have a strange and serious problem: I can't connect to hidden WiFi's.
I'm with a LG G3 D855 10H (no newer versions available).
At work we use a hidden WiFi without password but with Juniper VPN.
When I type in the network name and save it, it tries one time to connect, then my LG G3 shows "not in range". After a few seconds, the WiFi is on the top again with a very good signal.
When I try to connect again, it shows "not in range" again and so on.
I tried it at home and created a hidden network and it was reproducible.
Anyone else has problem with this?
Many thanks in advance for your help!
Best regards,
Jake

Now that is what you call a 'special' post!
Would you care to explain how it was resolved for the people that have the problem.
My problem still exists, but isn't urgent anymore.
I found out, Android itself have problems (or restrictions?) to hidden WiFi networks.
I also found an app names HiddenSSID Enabler, but it seems it didn't work for me (or G3?).
If someone has a solution it still would be very helpful fo rme and the rest of the community.

I have logs posted in my first post, WIFI DESTROYED TWICE or there abouts.
I've had to resort to DATA and its killing me haha i think i am getting close to fixing it, well i think i may be closer than you two and can one of you kindly take the lead as im reinstalling windows and i haven't gamed in 6 days :|
/system/etc/wifi/WCNSS_qcomcfg.ini
then the problem is complex but i am sure it is something to do with gEnableApProt=1
Offshoot fix, reinstall using googled imei number that doesn't have a flag or some how fix the flag <READ A FEW DAYS BACK>
I think actually the program that stuffed me was Airmon by maxters. It asked me if i was pro and of course, i said yes. Who would simply click no? I know a ninj wouldn't click no. I think there is a manual reinstall to link to it again i find the modem in its own partition having a chill, most likely trojan/backdoor and pwning everything around me.. I had three encrypted vpn backdoors and escalated accounts on my computer I paid the 5$ for the binarys, i think i paid 5$ for the back doors.
Not to sell Airmon out though.. Rooting our phones and accessing countless forums and websites really does leave us rather "xposed" some other cuplrits may be dsploit, ROM manager, linux Deploy/kali, Pamn IP scanner, system app remover pro, busybox pro's (Stephen/JRummy) or CMinstall/accessing the forums and trying to install cynagenmod / twrp recovery. I'm probably going to go with..... Airmon/Linuxdeploy or uninstalltool. But may have just been my IP logged and i hit a booby trap script along the way.
You guys done anything of the sort?
/Thread killller
Neither I understand what you are talking about, nor am I (as not native english speaker) good at "sentence guessing".
I have a rooted phone - of course.
But I'm pretty sure my WiFi is not destroyed...
