I've recently made a modpack with 126 mods. I have also made my own VPS server with said modpack. I created it mostly for my friends to play. However I myself have run into an issue, where if I try to join my server I most of the times get an error message.
Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host.
My other friends join mostly without any issue as well as my Gf that is connected to the same wifi. I have also noticed that if I join after a long time there seems to be fewer issues, but if I join in and then relog the error pops up and I am no longer able to join in. (I have tried to spam Join button for around 2 hours)
It feels like a network issue of some sort and I am kind of hopeless as what to do because I've searched everywhere for an answer. Could anyone, based on the logs that I attach or any information you will need from me to hear, help me with this problem?
I think that the crash log is the most important because it looks like that I can join a server without any issue the first time, but then when I leave I get an error message thanks to VanillaFix mod and the error is the crash log. I am not sure what it means, but I think it is probably the main source of the problem.
Thanks to anyone who takes the time to reply or help me, I am grateful for any help.
