So, I've been trying to host a 1.12 modded server. I'll be on it just fine for about 5-10 minutes until me and the other guy get disconnected with this error (link below). Once this disconnect happens, my wifi gets disconnected from my only my pc (No other devices are affected, and my pc still shows connected) and doesn't work until I disconnect and reconnect. I can confirm that it isn't a mod causing this as we removed chunks of mods at a time and every time the server had this same error. Each mod was removed. I have the latest forge installed. This never happened when I hosted our 1.7.10 server a while back. How can I solve this?
