Sidecar no longer working (miscellaneous error -455)

Sidecar worked yesterday. Had to issues sharing my screen to either my iPad Mini (5th gen) or iPad Pro (4th gen). So this morning, I go to connect and I'm getting "miscellaneous error -455". The interesting thing is that the iPad device (either one), goes to a lock screen when I go to connect. It wasn't doing this yesterday. I've already rebooted ALL devices including my Mac Mini M2. Also turned off Universal Control and turned it back on. Any ideas?
