The server list in steam was a great suggestion. It doesn't find the server automatically but when I Add a Server and put in 192.168.47.3:57550 it immediately changes it in the list to "ATLAS Docker - (v402.6)" and shows the map as Ocean and Game as ATLAS, players 0/38, etc. But if I try and connect to it, it shows:
So - I am thinking this is not a port forwarding problem on my router, as I am going directly to the server. As far as I can tell, the Atlas server is running fine in docker. It is definitely listening on all the ports:
and unRaid opening/bridging those same ports for TCP and UDP..
So I am unsure what the disconnect currently is. At one point in my testing when trying to connect it asked for the password and actively directed my running Atlas game client to point to the server but failed to get the server info and failed at that point.
The only thing I have changed on your image is in the ServerGrid.json file - I changed the WorldFriendlyName and the WorldAtlasPassword entries.
Any ideas would be appreciated.
