My friend can't connect to my server

  • Hello everyone

    This is the message my friend receives whenever he tries to connect:

    Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: Index: 27, Size: 5

    This is what I receive in the console:

    Internal Exception: io.netty.handler.codec.DecoderException: The received string length is longer than maximum allowed (20 > 16)

    My friend is using T-Launcher on Windows, while I am using the official launcher

    I could still connect to my Server

    The server has offline mode enabled (cracked) and is in version 1.15.2

    The server uses Spigot with the following Plugins:



    My friend was able to connect twice, then he received the previously mentioned error message. Anything I can do about this?

    Thank you.
