I was going to just ask for help with this on discord, but I cannot link my account due to not being able to get on the server. Whenever I try to join the server I get disconnected with an error that seems to be telling me to register? I do not remember exactly what the error/kick message is but it is something along the lines of ERROR(word I can't remember)REGISTER. I am not sure what to do and it is quite upsetting, as I enjoy playing on the server and would like to continue.
This was due to the server being incompatible with 1.16.2. The servers now have compatibility except Carrot, so if you wanted to play on Carrot, you may need to join on 1.15.2~1.16.1 until the next restart to join.
