Sorry for the late response, Steam isn't notifying me about threads.

I'm not entirely sure what would cause this - does the map work when you host it normally on a local server?
I don't have experience with server hosting, but my guess would be a server configuration is causing the problem

Bump.

Experiencing the same problem. Have tried numerous server configs, etc. Server says it's connected to Steam, but I can't get any of the group server/lobby stuff to work, but can still join via `connect [ip addr]`.

I then get "can't find map/helms_deep-*" when trying to join, and the only thing that works is extracting the contents of the VDK to the client (e.g. put the map in maps/), which lets you join, but there's no scripting / items when you spawn.

It feels like you're just playing vanilla L4D2 but with the specific map. I'm not sure how plugins and scripting work, but it seems like there needs to be some way to initiate this on the server. Is this what a lobby does? Is that the problem?

I may be late for it.
But for dedicated server to host this map, you must also specify the game mode param after the map name.

E.g:

The "survival" after the map name is required for the game engine's internal to actually host the map with correct game mode, the cvar "sv_gametypes" or "mp_gamemode" isn't working correctly for this case.

Can you break it down in very simple terms how to host the map?
