I have the same problem and this topic describes it exactly what happens in my situation.
I am running version 5.3.4 Build 1183 of the Pulse client and Cisco Jabber 10.6.2 (Build 59142) on a Windows 10 (1709) Laptop.
I found out a workaround. I have disabled "Cisco Media Services Interface Protocol Driver" on "Pulse Secure" connection. I don't know yet the impact on the Jabber application, however both Jabber and Pulse work.
I'm facing the the same issue on Pulse Secure 5.2.6 (977).
I don't have Jabber nor any connect installed - but I've Mcafee installed.
can you advise how to fix this issue please ?
the problem can occur if you have a Microsoft Wi-Fi Direct Virtual Adapter
You can fix this problem by disabling the Adapter:
Then, it should work.
