Last weekend, we performed the upgrade of our platform from the version 9.1R1 to 9.1R3. The client is supposed to be upgraded automatically to match with the server's version. For some users, the client upgrade were failed and those users were not able to connect to the VPN the usual way. When they try to connect to the VPN from the Pulse client, the moment when Pulse client launch the connection, the connection disappears and the message "The Pulse Secure Service is not running" is shown in the Pulse client. The user has to close the Pulse client then re-open it then the connection starts to work. But every time they want to connect, they have to repeat this steps. We tried to remove the Pulse Secure Client and reinstall it but it does not solve the issue. To fix this, we have to uninstall all the Pulse components (client, host-checker, installer service, activex, ...) then reinstall the Installer Service and then Pulse Client (by going to the VPN site). After that it starts to work again. For some users it's even not possible to uninstall and reinstall the client (it keeps rolling back at the uninstallation/installation). We have this issue on windows 10 PC (1803).   Can somebody please help ? we already open a case with Pulse but it will take time for sure. ... View more
