Failed to connect to the Pulse Secure Unified Network Service on Mac Os High Sierra 10.13.6

[guojy21]

I've used Pulse Secure(9.1.3 1313) for two years, but suddenly it doesn't work just after restarting my computer about month ago. It showed "Failed to connect to the Pulse Secure Unified Network Service" whatever I wrote in the blank "server URL". I tried kinds of methods but still cann't sovle the problem. There is aslo no antivirus / antimalware product on my computer.

Even when I tried to open and save the pulse client logs, their is no respond. So I copy this from the package cotents and hope it would help.

Thanks!

Thanks. I use pulse secure to connect our campus network, I've asked staff for help while he cann't solve this problem.  I don't have the serial number to open a case, I will try if staff could give me the massage.
