I just installed WFA 4.2 on a Window2012 system, and now I can't login to the WFA GUI. It asks for username and password (which I know I am entering correctly), but it says that they are invalid. Assuming I might have entered the passwd for admin incorrectly when I was in the installation wizard, I re-installed the software THREE times, with the same result. Assuming it might be a browser issue, I tried chrome, firefox, IE and edge (to no avail).
I have already verified that McAfee is not the issue. And there is nothing regarding failed logins or https issues in the WFA's wfa.log, server.log and wfa_client.log.
Please help!
