Cisco Collector appliance GUI not working

[rloyola22]

Hello Cisco Team,

My GUI access is not working since yesterday. I've already tried rebooting appliance, service cspc restart and even shut down the VM instance with no luck.
Please check image attach:

Please let me know how to proceed and re-gain GUI access.

Update:
Apparently this was due to multiple discoveries made at the same time.
Most of them pass but one get hung which may be cause the GUI issue.
