side car works on my MacBook Pro (2017 Touch Bar) but not on my Mac Pro. I get the message "Unable to Connect to iPad. A miscellaneous error occurred (-501)". My iPad Pro then switches to the Lock Screen, so they are talking, and both can see each other. I can find nothing anywhere that relates to error -501 apart from some reference to a string array. any one got any ideas?

this has happened from. Catalina right through to Big Sur.

I just can add one hint, if you are using several users on Mac, firstly you must disconnect your ipad from one user to use it with another one. Otherwise you will get an error -501.

Also using Cisco VPN connect leads to this problem too because of IPv6 known problem.
