When logging in to iMessage on my Mac Mini using my Apple ID (which works on my phone and elsewhere) on Big Sur 11.6, I repeatedly get 'An unknown error occurred'.
Mac mini 2018 or later
Resolved. from one of the suggestions, turned off wifi and tried again - somehow that resolved the issue.
Thanks to all.
You are welcome.
