I am unable to make a UDP tunnel

I am running a minecraft server for Java edition, and trying to use Geyser MC to allow bedrock players to join, however I must set up a UDP tunnel for this. Unfortunately, when I try to register UDP, it asks if I will not use it for any malicious purposes. Then it resets without registering a UDP tunnel.

Do excuse the late reply, but make sure you’ve clicked on the UDP (or TCP/UDP – whatever floats your boat) option explicitly – even if it already says that it’s selected.

There’s an odd bug in the website where an option will be initially selected, but not really “registered” per se.

After the malicious purposes question select the UDP tunnel again.
The question will not be asked again and you will proceed to creating the tunnel
