Unable to join Forge server

[DutchDJ]

Hi Velocity team!

I'm getting an error when trying to join, I think I've got everything configured correctly but it's not working.
I'm running Ambassador and Proxy Compatible Forge since the modpack is 1.20.1 (Valhelsia 6) without Velocity I am able to join the server without any issues.

Hopefully we get this resolved :)

It looks like the same bug I am experiencing. I wrote some additional context in #1370
