Symptoms
The NetWorker VMware Protection integration is configured with the vProxy Appliance. The nsrvim is intermittently failing during the execution indicating that it is unable to get the latest environment information for the vCenter server. The nsrvim command is failing within a second of execution with a generic HTTP error from the vCenter server. This is intermittently impacting the VMware backup workflow executions and the NetWorker Management Console VMware view.
The daemon.raw log shows:
