How are you able to connect to 1.21 servers in the first place? I'm always getting the message "This version is not supported!" (built by myself from lastest master branch).

I tried Minecraft 1.18 and it worked. The server runs ViaVersion and ViaBackwards.

Server version : Velocity 1.7.2-1.21 (protocol v767)
Cannot connect to the server : This version is not supported !
Server version :
Restarting Minecraft Console Client...
Settings have been loaded from MinecraftClient.ini
You chose to run in offline mode.

Type '/quit' to leave the server.

The server needs to add ViaVersion and ViaBackwards

Ok, I thought there already is support for 1.21. Using ViaBackwards and version 1.19 I can join the server. A bit overkill for my server having to install 3 additional plugins (+ViaVersionStatus for unaware players) but at least it works and I can AFK at my farms again.

I can't join the discord because the invitation in GitHub is no longer valid and can't get help
