But, if I was, it would still not change that the port is not binding, which must be actively done inside the application process. Does the game log if the application fails to bind to the port?

> likely the problem is as you described that for some reason your server is blocking or not binding to 8766 The host machine itself is not blocking binding to port 8766 as I was able to successfully bind netcat to that UDP port. pzserver@localhost:~$ netcat -l 8766 test ^C pzserver@localhost:~$ netcat -lu 8766 test ^C (note that those tests are received from other hosts) > could you try installing the "Steam Client" and see if that helps? I'm not sure what this means, but I had previously installed steamcmd and I just installed steam, itself, no joy. FWIW, the server is definitely connected to steam tcp 0 0 MY IP:34549 162.254.193.102:27020 ESTABLISHED 21494/./ProjectZomb that IP belongs to Valve: https://whatismyip.live/ip/162.254.193.102 > If it doesnt help, can you check if you have any "steamclient.so" file in your server folder? yes, its in a few locations: pzserver@localhost:~$ find . -name steamclient.so ./.steam/sdk64/steamclient.so ./.steam/sdk32/steamclient.so ./.steam/steamcmd/linux64/steamclient.so ./.steam/steamcmd/linux32/steamclient.so ./serverfiles/steamclient.so ./serverfiles/linux64/steamclient.so ./serverfiles/linux32/steamclient.so

> Are you able to connect through the favorite when you have the IP there and not the DNS name? no > And can you share the whole server log? attached, the rcon connection was me using netcat to test that port 23-05-22_23-51-45_DebugLog-server.txt

Also interesting, but probably not super relevant, when I enter the favorite using the IP, I get all kinds of server data like ping, whitelist, players, version, but when I enter the favorite using the DNS name, I don't get any of that data.

What are the specs of the server? its a linode with 4 cores and 8GB memory What OS is the server running on? I have tried this on ubuntu 22.04 and ubuntu 18.04 What is your connection speed? N/A its good enough to initiate a connection Did you try to fix your problem and how? yes, I have tried to install using the linux GSM script, and using the wiki https://pzwiki.net/wiki/Dedicated_Server What's the issue, exactly and what did you try to fix it? the exact issue as deep as I can debug it is that the server is not binding to port 8766, worth noting that when I run the server and the client with -nosteam, that the connection works, but this is undesirable Is the server being run on a VPS or home computer? it is being run on a linode Some more logs: LOG : Network , 1653349954019> 50,605,942> *** SERVER STARTED **** LOG : Network , 1653349954020> 50,605,942> *** Steam is enabled LOG : Network , 1653349954020> 50,605,942> server is listening on port 16261 LOG : General , 1653349954020> 50,605,942> LuaNet: Initializing...
