Linux desktop client (randomly) losing login on reboot

Troubleshooting
1

Summary
Linux desktop client (randomly) losing login on reboot.

Steps to reproduce
Version 5.2.2 commit: 2030c66
Unable to reproduce because happens randomly.

Expected behavior
Not to loose login.

Observed behavior
Losing login
Sometimes i start my notebook and I have to login again.
Im using Mattermost since ~2 month.
The lost login problem happen like 3-4 times already.

Reboots (crashes?)
Also i have the feeling that Mattermost causing suddenly reboots on my notebook
and on the notebook (mac) of a colleague too.
Why I think that: we both no had random reboots or crashes at all.
And all the sudden we both have this sometimes.
The only thing i see we have in common is: we switched from RocketChat to Mattermost.

Today i started my notebook as every day,
I logged in (notebook login) and like 1 min later I had a reboot (crash?).
After the reboot I had to login at Mattermost again.
(The login works without any problems.)

Client environment

Server environment

Hi @cottton and welcome to the Mattermost forums!

Can you confirm that the server’s SiteUrl configuration option is exactly what you’re putting in the Server URL of your desktop client?
The desktop app saves some logs, so it would be good to check them to see if you can find segfaults or anything related in there that might help diagnose this issue, although having a linux system reboot usually is something more severe, like a kernel module bug which could be an indication for a graphics card/rendering issue, so you could try to disable graphics acceleration in your Mattermost client to see if that fixes the reboots for a while.

Yes.

Logs

~/.config/Mattermost/logs/main.log (the only log found)
This is from Feb 20th, when i connected to another WLAN and had to login again:
The part with ERR_INTERNET_DISCONNECTED is interesting.

EDIT:
All unique errors codes found in the complete log:

Error: ERR_NETWORK_CHANGED (-21)
Error: ERR_INTERNET_DISCONNECTED (-106)
Error: ERR_NAME_NOT_RESOLVED (-105)

I have the feeling that the autostart could be a problem.
Something like “staring too soon” or so. And perhaps the stored login gets overwritten then?
I disabled the autostart for (old)RocketChat and Mattermost in the system (linux settings).
I then saw on the next reboot that mattermost still was auto starting.
I disabled the mattermost autostart in the mattermost app (“start app on login”).

so you could try to disable graphics acceleration in your Mattermost client to see if that fixes the reboots for a while.

First i will leave it on NOT autostart to see if the problem still exists.
If still exists then i will try with the graphics acceleration setting disabled.

So far no lost login.
I will post an update as soon i know more.
Thank you for your time =)

Yes, these messages clearly indicate that Mattermost has been started before the network was available, but you should not need to re-login then.
Is there maybe a HTTP landing page or something like this in your WLAN which would cause the Mattermost client to think that the server connection was invalid?

Let’s see if removing the autostart helped :slight_smile: :popcorn:

I forgot about this …
no more lost logins happen anymore.

I did not try to use auto start for mattermost ect.
Im just happy that everything works.

Thanks for reporting that removing Mattermost from the autostart helped - marking this issue as resolved now.
