Can you get into /logs? 
Maybe there is some clue of what happens
can any of the other admins log in ?
Note: you should get a free MaxMindDB key.
have you tried safe mode ?
Ufortunately, safe mode does not make any difference.
Can you check the browser error logs (F12 → Console) when you try to open the admin page?
can you access mysite.com/admin/upgrade ?
if so, try and run a update all. then log into admin again
Problem solved. Thank you all for your suggestions and help. Great forum!
I was able to log in as admin after upgrading docker_manager.
I am posting my reply here because it seems that a separate thread was opened yesterday where @IAmGav helped me solve the problem. Thanks again!
go into admin > settings and search for use admin ip allowlist and disable it
