I also noticed that in the URL it loses the site link IE the login is "/suite/sites/phs-users" and with the 403 error the link is "/suite/sites".

The corresponding error shows up in the server.log file:

ERROR com.appiancorp.security.authz.Forbidden - Could not log forbidden URI. forbiddenUri=/portal/portal.jsp, originalUri=/

Things I have tried to do to resolve this issue:

5. The error still occurred

Then I did the following:

I tried going into the si...
