Symptoms
On attempt to generate Office 365 Reconciliation Report the following error appears in CP (branded URL case):
"Unknown error occurred"
and in browser console:
The corresponding service is not available at the moment. Try again in 2-3 minutes.
Same time, Reconciliation Report generator works fine locally via [backnet_ip_address]:8080
It could be seen in the sitelog that the Reconciliation Report itself was successfully created on the Endpoint side:
