For those having issues with Project Zomboid (PZ). Took me a second to understand what was happening. If ports 16261 16262 and 27015 says Not listening, but you added them to the ports in the container settings and it's probably the first time loading, the startup will hang until you add a admin password. meaning, either add a password on the configurations or go to the console and type a admin password, to move forward, once that is completed you should be able to get the server working.
