A fatal error has occurred, this connection is terminated

[Big_Energy]

I installed Opis on my server and client. When I connect to the server, I am kicked "A fatal error has occurred, this connection is terminated"

I think I have the same problem - the client is disconnected when it tries to connect to the server - heavily modded setup (200+ mods)

client logs: (Caused by: java.lang.UnsupportedOperationException: direct buffer) https://pastebin.com/JwarrHip

server logs: (io.netty.channel.unix.Errors$NativeIoException: syscall:writev(..) failed: Broken pipe) https://pastebin.com/1HGrY5NX
