#epiconlineservices — Public Fediverse posts

I have been fighting a weird multiplayer bug in our current project for weeks now.

After leaving the game in the background on a certain platform for more than an hour, the game would loose connection to the #EpicOnlineServices right after bringing it to the foreground again.

Turns out this is a bug in the #EosSDK, and has been fixed in 1.17.1.3-CL44532354 - 2025-aug-12.

Beware, that this version is newer than the one shipped in #UnrealEngine 5.6 (I think...).

So. First we have two (three?) things we need to fight.

1. #EasyAntiCheat
2. #EpicOnlineServices, as at first sight it seems it uses it for matchmaking porpuses?
¿3?. Savegame server? Savegame is cloud stored AFAIK, so maybe they're using a custom solution in this one

# 1. EAC
Easy Anti Cheat games usually have a bootstrap exe which sets EAC and launchs the payload exe which contains the game. In VHS case it seems launching the payload exe directly works. Since it doesn't seem to actually check if EAC is properly set? (weird)

2. EOS
Fortunately, someone has made an emulator for EOS so we're covered in that point. Launching with the emulator right now gives either a generic connection error or a "Cloudrun error" whethever that means, I'll leave that hanging for now.

3.
Right now I'm try going to try and do something about Nº3 and MITM myself to check what is the game doing with the savegame. The only thing I know right now is that it's talking with an AWS server
