Backup job fails with “An internal error occurred during execution, please contact Vizioncore support if error persists. Error message: The operation has timed out“.
This issue can persist in both vRanger Pro DPP 4.2.3-15522 and 4.5.0-15937.
Example: Putty to ESX host works but authentication takes about 40-50 sec or longer than normal or expected.
Misconfiguration of or removed Primary DNS server can cause this kind of slowness.
On the ESX server where the vm lives the primary DNS server was set to a DNS server that no longer existed in environment.
To correct point the ESX server to a new or existing primary DNS server.
