    Both my friend (the initial owner) and I have the right to launch the server.

    They get following error: Internal Exception: io.netty.handler.codec.DecoderException: Java.lang.IllegalArgumentException: Unknown recipe serializer adorn:brewing every time they try to enter server.

    I don't get any errors, everything works just fine. Their mods folder contain exact same files as mine (copied), so all mod versions are correct.

    The logs: https://mclo.gs/dY5ztAb

    Any help/explanation welcomed!

    Ask them to share their client log:

    1. open your minecraft installation path

    (enter %appdata%/.minecraft in the file explorer )

    2. open the logs folder

    3. open the "latest" or "latest.log" file with a text editor

    4. copy and paste the content of the file to https://mclo.gs/

    5. send the link here

    Thank you! We read the logs and found the problem. Apparently, it was the TLauncher.

    Reinstallation helped, so everything is fine now :)
