So, long story short, I made a minecraft server for me and my friends. I got a mod list set up and verified that everything worked, got it all working perfectly, and it was all hunky dory. Just today, I finally got my port forward working properly, and I've come across a little bit of an issue. Somehow, my friends can connect to the server without issue and do whatever they need to do, but I cannot. Over local network, over a VPN trying to connect to my own network, no configuration that I try yeilds any results. The errors I'm getting aren't always the same, but it's always something along the lines of "Internal server error" or "client software closed the connection." I've reinstalled Java, I've reinstalled curseforge, I've reinstalled minecraft, and it still does this with every fresh copy. The server side error says "Wrong distro for dedicated server" but that doesn't make sense because I'm running java 8 Update 301 x64 on both machines.
(I'm running MC 1.16.5 using Forge 36.2.2)
