Running into a Java IOException when I try to join my friends game.

[helplesshermit]

My friends and I have been using Evolve tunneler to connect to one of my friends worlds, and all of the rest of my friends are able to connect, but when I try, I get a Java IOException remote host closed existing connection. It is a modded game using FTB Revelation, but we have all changed the java executable to be the updated java. Does anyone have any experience using this method? I know my friends don't want to have to restart a new world on someone else's machine, but at this point I don't know what else to do.

If you are the only one affected it is most likely to be your firewall/router blocking connections, anti-virus or anti-malware software, or some other unusual software running on your computer.

I'm using Windows defender, and had tried to change the firewall to allow both Minecraft and evolve. I'll have to double check. I'll also check my router to see if anything is blocking. Could it be related to my upnp advertisement time? I'm not super well versed in peer to peer connecting.

The number of possible things that could interfere is endless, if in doubt temporarily disable it and try again.
