Problem Description

Issue

I hard to rebuild my Debian 12 server for AMP. Deleted game instance and reinstalled it. Game was L4D2. After installing and updating, it hangs. I can walk away and come back later, and it’s still stuck on starting. I stop the instance and restart it. It still shows Starting.

Reproduction Steps

  • Reboot server, watch AMP and instance start
  • Instances shows starting in the upper right corner of the screen
  • Walked away and checked 15 minutes later and it’s still starting
  • Shutdown instance and restart it. I get the same results, it hangs.

Now it’s failing with:
You must select a specific IP address for this server to function correctly in AMP. Selected: 0.0.0.0. Loopback (127.0.0.1) and Any IP addresses (0.0.0.0) are not supported. You must edit the ‘Application IP Binding’ setting network settings from ADS using the pencil icon and select the ‘Network and Ports’ tab.
When I tried to set the IP, the dropdown is blank.
