I'm having issues where users cannot connect to a multiplayer server that I'm hosting. The server is listed in the public servers, but when a user tries to join, they just get the error: "Couldn't establish network communication with server". Now I know you might say that it's port forwarding etc. but this is where it gets interesting...
I've got a 0.16.51 server and when I start that up (on the same host) it works 100%, people can connect and I didn't even have to forward any ports. The issue appears to only be with the 0.17.x servers. Does anyone know if there were changes in .17 that would explain this?
I've re-downloaded the server files and set up new servers with new saves and I'm using the same settings as the .16.51 server.
Windows firewall is completely switched off on the server. The server log does not log anything when a user tries to connect.
