Using Office 365. Having Skype for Business Clients in my network. Have been working but since yesterday something has happened.

My problem is that I cannot log in using my Office 365 account in Skype for Business Client. For test purpose, if I insert myself on the Transparent Mode Skiplist it works, I can log in.
Skype for Business Client and Office 365 is apparently not easy to maintain when scanning SSL in UTM. I cannot see any blocked pages in the UTM web proxy log.
Using Office version 1805
How can I fix this? Anybody?
