Unable to join 25w14craftmine or 1.21.5 servers with Craftmine client

[Cube-593A]

I was able to join the server directly, but somehow joining via Velocity just resulted a "Disconnected". (both 25w14 and 1.21.5)

There were nothing but only "Disconneted" in client side logs.
[19:34:27] [Render thread/ERROR]: Can't ping 10.0.0.59: Disconnected

And no any errors or info were presented in Velocity and backend server consoles.
(I suppose that the connecting request didn't reach the backend server, nvm.)

Anyway, velocity did occured some errors(NoSuchMethodError) when I was trying to join 25w14acraftmine server with 1.21.5 client.

UPDATE:
I've changed the CI built versions of ViaVersion and ViaBackwards to that maybe matches ViaAprilFools's to avoid NoSuchMethodError.

I tested with a vanllia version craftmine server instead of a fabric one, and it worked fine, while I still cannot connect to the fabric backend server due to this error:

Missing registry data for unknown dimension: generated - this doesn't sound right.

Something similar is happening with me and viaproxy
