Problem description
Unable to deploy the VMware Backup Proxy. Error Code: VMWARE263
Cause
The deployment failure is traced to an issue with the Open Virtualization Appliance (OVA) file. Logs show that the process fails during the disk upload phase (upload_disks), which suggests that the OVA file is corrupted or incomplete.
Although the log error “Name or service not known” appears to indicate a DNS issue, this is considered a secondary symptom. The primary cause is that the deployment script cannot correctly read or process the corrupted OVA package. As a result, it is unable to determine the required network endpoints for data transfer, leading to the name resolution error.

Resolution
Download a fresh copy of the Proxy OVA manually from the official Druva download portal from here:
Verify the integrity of the OVA file (for example, by checking the file checksum/size) before deployment.
Use the newly downloaded copy of the Proxy OVA to deploy for a reliable and successful installation.
