When I upgrade using ps-pulse-linux-9.1r11.4-b8575-64-bit-installer.rpm the UI starts but no entries are shown or can be added. I suspected a missing font or library, but ldd /opt/pulsesecure/bin/pulseUI shows nothing is missing nor does strace. However strace does say "DBUS api call failed with code: 2 - message:GDBus.Errorrg.freedesktop.DBus.Error.ServiceUnknown: The name net.psecure.pulse was not provided by any .service files".
This is on a completely up-to-date RHEL8 desktop that was rebooted after the upgrade. The previous VPN connections are not displayed and attempts to add new connections also do not appear in the UI.
The only solution that I can find is to rollback to the older 9.1.10 version.
One quick update: My attempt to rollback didn't fix the issue. So I am now unable to use my VPN client at all.
