I'm unable to join my minecraft server. If i try to join it gives the  error "io.netty.handler.timeout.ReadTimeoutException". Its only on my server. It is running paper 1.20.4. I get the error on java and bedrock. My java version is 1.20.4 my bedrock version is 1.20.81.

Yeah this looks like a Minehut Bug

I am playing 1.12.2 with spongeforge and were trying to use a mod called davincis vessels, which adds blimps, and when I sit in one and try to fly around with it the server kicks me and gives the message: "flying isn't enabled on this server" even though I have enabled it and restarted the server and tried multiple times.

I don't know what to do?

Could you explain what the issue is? (Any errors?)
