Since this morning, the access to Microsoft 365 Admin is impossible.
I had an update of KIS this morning : 220.127.116.119b
So it seems it is the cause.
Message in Safari : “Safari can’t establish a secure connection”
Please do something quickly

I’ve heard from Kaspersky Technical Support again and they informed me that the issue should be solved now. I switched back on the "check secure connection (https).." option in the preferences and checked all the websites - and they’re working now! Seems that the issue is solved! Hooray!
Would advise you checking if it works for you too. “
