Hello, Trying to run the Project Zomboid dedicated server on Unraid. Fully stock docker install, changed nothing on it. Also tried reinstalling because of the problems. Forwarded ports based on the comments, (16261-16262 TCP+UDP, 8766-8767 TCP+UDP, 27010-27040 TCP+UDP and 16263-16270 TCP) but still unable to get it to run correctly for multiplayer. I know the forwarded ports work fine as I have tested setting up other services on those ports and they work without problem. I also have several other servers and services of various types on multiple computers using port forwarding without any issues. I myself can connect fine from within the LAN, both with Steam relay on and off. Players over internet cannot connect, however, they are just getting "Server failed to respond" trying both port 16261 and 16262. From the router I can see the rule for these ports trigger, 58 bytes of data is transferred every time someone tries to connect - but they get nothing and I see absolutely nothing in the server logs, it is as if they never tried connecting at all. They have tried both stream relay on and off. Anybody have any tips on what to try?
