Hello Dmanuel,
Pulse Secure Setup Client is a component which allows end user to launch SAM, NC, Pulse and other PCS component via a web browser. There are some errors in the debuglog.log which support will need to review to get a better understanding of the root cause. You can try uninstalling the Pulse Secure Setup client from the Add/Remove Programs to see if this helps. If not, please open a support case.
