@arc said in Sudden "Lost connection to server", with no indication of connection issues:
This specific message refers to desync between you and the server meaning an actual connection issue whether it is packet loss, high latency to the server, firewall or other security software blocking the game or intercepting the connection, Windows related networking issues, and so on.
It is also possibly that the server crashed/froze which would result in this message in some instances (it usually should spit Timed Out message instead).
I doubt it's a typical desync because I can be playing literally fractions of a second before losing connection with no sign of desync --- as confirmed by a friend I played with when I dropped and my own experience (e.g. everyone is changing direction of movement [implying I'm getting recent movement data], I can actually kill things, stuff like that).
It's not security software --- I've installed more things since (though no security software, specifically), but at the time of first issue, it was a completely fresh install of Windows ... Insurgency was one of the very first things I installed (right after Steam [duh], Firefox, and a few other basics such as Notepad 2). Windows Firewall was already offline at the time, because I rely on pfsense for that.
It's not a server crash/freeze because my friend that I play with doesn't get dropped (or anybody else, for that matter).
Being a UE4 developer myself, I know how to (roughly --- obviously, details depend on the game) identify desync issues in server-client configurations, and I think this isn't it.
I can try recording a video of what happens (though it might not be clear that there's no "usual" desync before the drop, depending on what I'm doing ... that'll only be obvious if I happen to drop in the middle of a firefight). (see update below)
@darkuranium Are you suggesting that the game works on different computer in the same network ?
If you mean same physical switch, that's TBD (but all other games work). But it is the same LAN (and thus router & modem). The setup is roughly
modem --(GbE)-- router --(GbE)-- switch --(GbE)-- PC. Removing the switch out of the equation is not viable, so I can't test this.
I did since move the other (working) computer within the LAN, and can give it another shot, right after I redownload the game (it's now connected to the same switch as this one). That said, this is the only game I have these problems in, and I play many other online games (FPS or not) --- dozens --- with no sign of any connection issues whatsoever. So I doubt this is the problem, but I can still give it a shot for good measure.
Update: The video is now available. Note the low ping, and recent shots at me by the NPCs (and not full auto, either), implying no connection issues before the disconnect.
