We have a Barracuda Web Security Gateway 810 and since we upgraded to Firmware v14.0.0.012 last Monday 7/30 we have multiple computers getting blocked from random HTTPS sites even though the sites are white listed. wnct.com and google sites (like google drive and google maps) seem to be the biggest offenders. It seems to be completely random and tied to certain computers and not accounts as in I can access a site under my account on my pc but if I log into user A computer then it blocks me on their PC.
The sites work fine when the users go off site but don't work when going through the barracuda. Has anyone come across this and have a solution for it?
