Hi,

We have a mid size MEM 2006 hierarchy with 1 CAS and 3 Primary Sites.
Around a month back we had an issue with both CMG and WSfB not synching to Azure.
It turned out that CAS was missing a DigiCert certificate which was imported from Primary Site to make both CMG and WSfb work.

We again ran into the same problem where CMG works but MSfB sync has stopped working again.
We have checked with network team and there is no SSL/TLS inspection.
These are the errors in the logs ..only clue i could find about this was on a forum..which advised to "install Certificate and intermediate certificate for businessstore.microsoft.com on CAS "

Not really sure which certificates we are missing since this has been working and nothing changed except for upgrade to MEM2006 from 1910.
