CptPICHU

Oof. I solved it. For those who wanna know: I tried every single mod. There were some little incompatibilities that needed to be fixed. What exactly causes this error must be most likely tested out i guess...

Additional info: https://pastebin.com/dGKb70Be This might give some more info. Its the Minecraft Log itself.

Hey there. I am creating a modpack right now. It included 104 Mods for 1.16.4 The Pack launches just fine and working very nicely. However, a server including all of this does launch, but throws a lot of errors and when connecting to it, everyone just can't. And there is always this very helpful error message: [Netty Epoll Server IO #2/ERROR] [minecraft/NettyPacketEncoder]: java.lang.NullPointerException Without any mods, the Server launches perfectly and everyone can connect just fine so the server setup might not be the issue. What am i supposed to do here? This looks very upsetting to me because i really have no clue what this error message even means. You can take a look at log here: https://pastebin.com/x3bGbHa5 I hope someone has an idea what is going on...
