WebProxy status "DEAD"

Question

I have a XG-115 which was working perfectly and for a reason which i don't know or understand the WebProxy just died. I have made no changes to the configuration of the appliance, it just started having this issue after some time. Does anybody have a similar problem?
Also which could be the causes for this to happen and how can I fix it?

Guys i lost many hours on this, and try various things. 
 After i try to downgrade / upgrade the firmware, download new iso up to date and format again the FW, I have find the issue. 
 Go to Administration -> time -> Do not use NTP Server and fix the date/hour. Yes i know, you had already setup the time on the installation but it wasn't saved.

The time on the XG firewall is correct.

The device is new and just upgraded firmware from 17.5 MR12 to v18 MR1 
 I did not observe this until I tried accessing the services alert from the control center.
