I can't join any servers except for CubeCraft. When I try to connect to any other server it returns this error:
io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information:

When I refresh the servers, nothing happens
But when I try to join CubeCraft, everything works just fine.

I have tried several fixes which I found on YouTube, the servers still don't load.

I was able to play on servers yesterday, I don't know what happened in the mean time.

I have checked 1.13.2 and 1.16.1 and I experience the same issue on both versions.
