unable to log into Google for Mail

(copy/pasted this from my Apple forum message)

Hello all. Just got a new MBP with Big Sur. Migrated everything over from my last MBP, which also was Big Sur. Intel to Intel.



When I try to log into Google/Gmail, the browser page pops up, PW goes in just fine, and Google accepts it, but the Mac window to log into the account just spins and spins. Never accepts the connection.



Updated to 11.5.2, same issue.



Suggestions?



Update: Big Sur/Mail can't seem to log in or verify login info for any of my non-Apple mail accounts.

Just out of curiosity (and no idea if it will make a difference), but have you tried - rather than adding mail accounts directly through Mail, of adding these accounts through  > System Preferences > Internet Accounts first, and then seeing if you can access / add them in Mail > Preferences > Accounts?
