So a group of friends have made a public server, however I alone can't log on. I'm not sure why as my firewall is open to Minecraft. We've double checked everything and it seems fine, but for some reason I can't actually play.
According to my friends I can get in game, I can be seen and even damaged, however I leave only 1-2 minutes after I join. On my side it simply says it's loading the terrain.
The message that pops up is usually:
Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host
My Java is fully updates, so is my Minecraft version. I can play on my singleplayer and all other servers except for this one specifically.
Like I can see the server, full bars, I can even see who's on it at the time. It's not a RAM or space issue since we had like 7 people on there at once, and I couldn't even connect when it had 2 people.
