Troubleshooting when UMDS is unable to download patches

This post outlines the process of troubleshooting issues when Update Manager Download Services is unable to download patches.


  • VMware Update Manager Download Services is unable to download patches
  • When trying to initiate a download using vmware-umds -d command you see errors similar to:

‘httpDownload’ 4440 ERROR] [httpDownload, 732] Error 12175 from WinHttpSendRequest for url


The issue was resolved by changing the download URLS from HTTPS to HTTP in the C:\Program Files (x86)\VMware\Infrastructure\Update Manager\downloadConfig.xml file.

Download URLS:</ESXThirdPartyUpdateUrl</vaUpgradeUrl</ESX4xUpdateUrl

Hope it helps!
