Portainer can't login post update

[warlock00]

Hi,

Updated Portainer today to 2.21.004. Can no longer login.
Message: Failure - Unable to retieve user details: Unauthorized

When I login. I can see that it partially succeeds.
The /api/auth endpoint is a 200 ok. Normally would fail here if you enter bad user/password.
But then the /api/users/me endpoint is 401 unauth.

I tried reinstall with full delete to no success. Which suprisingly preserved login which is scary if you want to reset login after forget.

This is strange, I swear I previously tried every combination of http/https, fqdn/ip and passwords.

Solution:
Password was reset to starting password
I logged in using http://ip...:8181/portainer (ie. not https://ip...:5443/portainer)
