Periodically, Pulse Secure, when trying to connect, will just hang and eventually time out (this is on Ubuntu 1804).
The only way I know round this currently is to restart my laptop.
Is there a safe way of restarting all of Pulse Secure VPN client on Ubuntu 1804 (e.g. from the command line) without restarting my laptop?
You can try to use a bash script that is delivered with PulseSecure.
P.S. You can find more in help
Hope it will help you!
