Im facing this problem with the activation of Office365 through our company firewall Sophos XG 330.
The dialog box shows |We are unable to connect right now. Please check your network and try again later|
The firewall rule is for "full access" and defined for AD users group.
All the rules working perfectly , the web content filtering is ok, the O365 activation is the only problem.
We have 3 WAN Connectivities.
Intrusion Protection |None|
Web Policy |Allow All|
Application Control |None|
Malware Scanning (I tried already to disable all the options, most important the HTTPS)
SCAN FTP
SCAN HTTP
DESCRYPT & SCAN HTTPS
The rule is for Active Directory Users Group
The Microsoft sites for the activation of Office365 are already in the Exceptions List for the web for (HTTPS Decryption-Malware Scannin-Policy checks)
Now.... to see working the O365 activation the only option is disable the NAT & Routing Rewrite Source Address (Masquerading)
but in this way all the other browsing do not work!!
In the rule there is the definition for a primary gateway and a secondary gateway.
I'm trying to diagnose the problem with the Microsoft Network monitor but the parser for the new office are not presents and don't qualify the traffic.
The Microsoft Support and Recovery Assistat for Office 365 report
