Symptoms

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. When attempting to add a vProxy in the NetWorker Management Console (NMC), you notice that the NMC Logs section shows the vProxy become enabled, initiate registration, fail registration with vProxy to vCenter i/o timeout error, and become disabled / unavailable. The NMC Alerts section shows the vProxy is unavailable. MM/DD/YYYY HH:MM:SS nsrd NSR notice vProxy 'vproxy01.dellemc.lab.com' is now Enabled. MM/DD/YYYY HH:MM:SS nsrd NSR info VM proxy Warning event: vProxy 'vproxy01.dellemc.lab.com' is unavailable. MM/DD/YYYY HH:MM:SS nsrd NSR info VM proxy Info: Initiating registration of NSR VMware proxy 'vproxy01.dellemc.lab.com' MM/DD/YYYY HH:MM:SS nsrd NSR info VM proxy Warning: Unable to register NSR VMware proxy 'vproxy01.dellemc.lab.com': Received an HTTP code: 500, libCURL message: "", vProxy message: "Error received from vProxy ="500: Post https://vcenter01.dellemc.lab.com/sdk: dial tcp 10.1.2.3:443: i/o timeout".

Cause

The vProxy that is failing to register could not communicate with vCenter over port 443, causing the i/o timeout error when adding it to the NMC. vproxy01:~ # curl vcenter01.dellemc.lab.com:443 curl: (7) Failed to connect to vcenter01.dellemc.lab.com port 443: Connection timed out All other vProxies can communicate with vCenter over port 443. vproxy02:~ # curl vcenter01.dellemc.lab.com:443 curl: (52) Empty reply from server

Resolution

Open port 443 from the vProxy to the vCenter server. Remove the vProxy entry from the NMC and add it back to the NMC.NVP vProxy: Troubleshooting Network Connectivity For Backup and Restore OperationsNVP vProxy: How To Unregister/Re-Register a vProxy Appliance?
