Cause
This issue occurs during vCenter Update Manager installation if the server is set with a name that is not resolvable from the ESX/ESXi hosts.
For example, if you choose a Windows netBIOS name instead of a DNS name to identify the vCenter Update Manager server on the network, the hosts in the SCAN/STAGE/REMEDIATE operation returns the error: Host cannot download files from VMware vSphere Update Manager patch store.
Resolution
To resolve this issue:
- Select an ESX/ESXi host for scanning.
- Click the Update Manager tab.
- Click Admin View > Configuration > Network Connectivity.
- Click IP address or host name for the patch store and enter the appropriate IP address.
- Rescan the ESX/ESXi host.
Note: To permanently fix this issue, ensure the nslookup of the vCenter Update Manager server from the SSH session of ESX/ESXi host can resolve both forward and reverse IP. The DNS entry of the vCenter Update Manager server should be configured properly in the DNS server.
