Environment

VMware vCenter Update Manager 6.5.x

Cause

This issue occurs due to incorrect proxy settings or vCenter might have connectivity issues with the Proxy Server.

Resolution

• Check the connectivity between vCenter Server and Proxy Server using the below commands,
  • wget --no-check-certificate --connect-timeout 10 -P /tmp/ http://vapp-updates.vmware.com/vai-catalog/index.xml -e use_proxy=yes -e HTTPS_PROXY=http://proxyserver_FQDN:8080
  • wget --no-check-certificate --connect-timeout 10 -P /tmp/ https://hostupdate.vmware.com/software/VUM/PRODUCTION/csco-main/csco-depot-index.xml -e use_proxy=yes -e HTTPS_PROXY=https://proxyserver_FQDN:8080

 

• Check if the proxy settings are updated with correct details give only <FQDN_OF_PROXY_SERVER or IP_OF_PROXY_SERVER> instead of http://<FQDN_OF_PROXY_SERVER or http://IP_OF_PROXY_SERVER>

1. Go to VAMI admin page https://VCSA_FQDN:5480 
2. Login with root credentials and navigate to Networking > Manage > Proxy Settings
3. Click on edit Proxy Port> Check Test Connectivity 
4. Make sure the correct details are updated
   • <FQDN of Proxy Server> instead of https or http://FQDN_Proxy Server
5. Save the settings and Retry the download patches again.
