ESX/ESXi hosts fail to scan in vCenter Update Manager 4.1.x, 5.x, and 6.x with the error: Host cannot download files from VMware vCenter Update Manager patch store.

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.
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. Notes: To permanently resolve 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.Ensure that the Update Manager Server can connect to the host on port 902. For information on the port requirements, see VMware Update Manager Network Port Requirement (1004543).
Also, ensure that the default Gateway is set at the ESX/ESXi level. To check or add a default Gateway: Log in to vCenter Server using the vSphere Client.Select the ESX host and click the Configuration tab.Click DNS and Routing.Click Properties.To add a default Gateway, click the Routing tab and enter the appropriate IP address.Click OK.Rescan the ESX/ESXi host. vCenter Update Manager 4.1.x および 5.x で ESX/ESXi ホストのスキャンに失敗するESX/ESXi 主机无法在 vCenter Update Manager 4.1.x、5.x 和 6.0 中扫描
