Comment 20 for bug 1159361

I had run into this a few times previous and just for posterity ... for those seeing the failed authentication have you tried logging admin out and back in again?

What worked for me was:

1. Enable OPT_USE_AUTH
2. Go into users tab and change admin password
3. at main page of GUI select 'admin' then click log out
4. log in with new credentials
5. Everything worked

I then noticed it again when I came back to an already authenticated session (IOW didn't challenge me for a password for admin). The browser still showed everything fine and the cameras logged in etc but I got the socket errors in the logs again. All I had to do was foce log out admin and re login and everything was fine.

ymmv
