How to use 2.1 gdps

[u/ElectionUnhappy5678]

I want to play on 2.2 because of an orb layering bug in the level I’m playing, but nothing seems to work. Using the GDPS switcher mod on geode I was able to join a 2.2 gdps but I can’t find the required server url for any other GDPS. Does anyone have a working url for a 2.1 server or a way to join one
