Therere 3 days ago, a page in the internet with authentication stop to work.
Its a content site. After the login and password in https page, the failed message is showed. But if i type <F5> (reflesh) i get to gp in content page.
Ive redundant proxies one 3.7 and other 3.6 both happen the same problem. I tried clean the cache.
The accsses without proxy only NAT works fine.
Ill thanks any idea.
