  • Everytime I try to join my server, this error just appears for no apparent reason (that I know of):

    Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(1) + length(8) exceeds writerIndex(5): FooledUnsafeDirectByteBuf(ridx: 1, widx: 5, cap: 5)


    I have never experienced this error previously and it just started appearing today. Are there any fixes to this?


    If needed, here is the information for my server:

    IP: 1cLtFHrF87.aternos.me:58487
    Software: PaperMC

    Version: 1.19.4

  • Update: I just rejoined on the regular Minecraft launcher and now it just says...


    Connection Lost

    Disconnected


    That was literally all it said. Any fixes?

  • Try the dyn ip and are you the only one facing the issue on the server?

  • The DynIP shows the same error:

    Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(1) + length(8) exceeds writerIndex(5): FooledUnsafeDirectByteBuf(ridx: 1, widx: 5, cap: 5)
