Can't join UDK dedicated server while Steam is running

[dsoltyka]

Question for you guys. I've been working on this for a while and I'm beginning to think I'm wasting my time.

We're working on a UDK multiplayer game. Dedicated servers work fine and allow players to connect, however this ONLY works if Steam is NOT running. If Steam is running, it looks like the client connects and immediately disconnects from the DS. I get output like this:

NetComeGo: Open TheWorld <date time ip>
NetComeGo: Close TcpNetDriver_0 <connection info>

Connecting to a dedicated server while Steam is running works fine if using the UTGame.UTDeathmatch game type, just not our custom game. Now I'm not sure if there is something more I need to implement for this to work or if it simply will not work until (or if) we get a Steam appid.

Any insights?

DefaultEngineUDK under [OnlineSubsystemSteamworks.OnlineSubsystemSteamwork s] bEnableSteam. set it to false.

Is that implying that there is actually no way to have dedicated servers working without an appid if Steam is enabled? I have no problem disabling it, I just want to know if that is indeed the case.

Well you can except that the normal udk appid has so many people using it that it will reject connections.

Well that's an interesting problem. Ok thank you for that.

I haven't come across this problem.

Also, if you are trying to Host & Join on the same computer with Steam Enabled it won't let you join (as far as I've tried) because your UniqueID is set VIA Steam (AKA: The OnlineSubSystem) which means you're trying to join with the same UniqueID as the Server, it doesn't like to authorize you for that.

Now I could be wrong, but that appears to be the link. There IS a LANUniqueID located in one of the Config files (forget which one) but, I haven't figured out how that works yet. Just you know, FYI.

I considered that to be the problem as well so I installed a UDK Dedicated Server on a virtual machine with another Steam account. Same story, immediately disconnects.

Are you able to see logs or anything for the Virtual Machine's game? If so, try logging

PlayerReplicationInfo.UniqueID when you launch it, then check your client's version. If the UniqueID is the same even on the virtual machine, that would probably be why. If not, I'm not sure what else could bethe problem.

The log shows nothing of consequence on the dedicated server. Just the immediate open and close of the tcpip socket.

Is there anything codewise that needs to be implemented for this to work, perhaps related to the Steam online sub system? It works perfectly fine with UTGame.UTDeathmatch, but my game (which derives from GameInfo directly) has no luck. And yes, I've tried deriving from UTGame etc, no luck there either.

Perhaps a related question, does anyone know how to attach an Unrealscript debugger to a dedicated server? That would probably help.
