So, I turned on IPV6 in FAF settings, choose COTURN server Finland (no server was chosen before), turned on experimental debugger. And it started connecting 80-90% times (it's ok for me, because it was around 0% for the last week and much earlier). Maybe this information will help somebody.

@sheikah btw, if I ping these servers in CMD, everything works fine, no packets lost

@zorg-kirill said in FAF Client sometimes show error and stop connecting to custom/coop game:

To make it more clean and easy, I deleted all logs, launched SCFAF and managed to get an error from the first attempt. Here are screenshots/fresh logs:

client.log

ice-adapter.log

So, the error code is the same, but now it don't point at "game log" or any log. So there is another bug with wrong error alerts. And in my opinion, the main error might be somewhere in ICE adapter.

it's in lobby, like in this screenshot

Could it be the reason?

@mazornoob I have firewall off. And FA don't launch directly. And I even can't host new campaign games

Still the problem is present. Maybe get latest build from github and debug it myself? Tired of this silly error...

didn't help to me

Didn't find good vpn yet, but found another interesting thing: this bug also occurs when trying to host new game. So, i doubt it's vpn problem.

@magge I'll try later, after work.

It would be also good to make so that error alert would be more easy to understand. And maybe add game lobby reconnect feature, so that it will automatically try 3-5 times to connect to game lobby in case of small errors. It works by hands, when I connect to the same server a couple more times, but it will be quicker and more pleasurable just watching it.
