Hi @Mawix
According to your information, it is difficult for us to find what is the reason of this issue. Could you check if there is any error messages from the event viewer in the front end server.
Meanwhile, please check if desktop, Lync Front End and AD have time in sync. Then try to restart Skype for Business Server Service to see if it works.
thanks, problem coused hardening SSL/TSL
i rolled back my changes on this area and works
does Skype for busines support TLS 1.2 ( i have latest CU) ?
It has been a while, how is everything going?
If you have any update about this issue, please feel free to post back.
