Issue

When started the instance it does not raise the udp game port

Reproduction Steps

  • Press Start Button
  • everything supports except the udp game port
  • 20 minutes after… is still in red

I seem to be having same issue. Yesterday, or day before, everything started up fine. Now, both of the servers I tried get stuck starting at the same point. The game or mods have not been updated or changed, so that should not be issue either.

Last lines from the log, what I can see from the console as it doesn’t allow scrolling up:

Update: seems that the server started after about 2-3 hours. Way too long time to wait though, but issue may be tough to crack, as no changes outside of AMP updates have been done.
