But, when we're had Lync 2013 all systems are works. This issue started after upgrade Lync to SFB2019
Hi @Viktar Bachkouski
According to your description, this question seems to be related to SFB, so we would move the irrelevant tags.
Could you provide us a screenshot of the error message if has?
It recommends you check if there is any related error message in Skype for Business front-end server.
Besides, due to user can work well on normal network, this issue is more related to Cisco AnyConnect. So, it recommends you also contact the IT of Cisco for further help.
