Getting Permission denied to access this portal.

We have one user that can't login to projects even though access has been granted. This user can login to accounts.zoho.com but when login to https://projects.zoho.com/portals.do we get this error:

Unauthorized login to this portal

Permission denied to access this portal.
Check your portal URL again.

Sometimes we also get "server too busy".
