I've been playing OpenTTD for a number of years, mainly online since steam integration.
Up until a few months ago I had no issues with connection. I then changed my network after relocating.
I cannot comment if there are issues on other networks as I can't access a traditional network.
Now, I cannot connect to privately hosted games by friends & they cannot connect to games hosted by me.
I can connect to larger games on the miltiplayer tab just fine.
When connecting to a friend's server the progress stops on 2/6 authenticating until the connection is timed out. I am on a wired connection but to a wireless network (5g router).
I have read around and have tried firewall settings & other suggested fixes.
If there is any known issues or fixes for 5g routers and OpenTTD please reply, any response is positive
