Not without a mod sadly

Yee its odd! Sometimes i get that error or ERR_EMPTY_RESPONSE. Never happened to me before in dedicated servers :/
Another question! Do you know if its possible using MapVote to change game mode for example from survival to endless on the run? i can figure it out
Forrest Mark X  [author] 6 Mar @ 6:11am 
I'm not fully sure what the issue is as I've never seen Webadmin give a 401 error which is a authentication error
Metal ϟThunderϟ 5 Mar @ 6:14pm 
i saw you said u can use web admin so i did the configs, wrote 127.0.0.1:8080 in the address bar but HTTP ERROR 401 error appears. Any idea why? Port is forwarded fine.

Ooooh okay and thanks

If the host doesn't mind bugs and the clients don't mind having to manually connect using Open you can skip the DefaultGame step.

The mod is there to fix a few host related issues and force find a match to start a listen server

That's strange, I don't change the GRI where the music is played. I'll look more into it

For some reason, when I do step 11, the main menu theme disappears.
