The message may suggest that the server address could not be resolved, which means the server’s name could not be converted into an IP address, which is pivotal for network communications.

Common Causes of 0x80072EE7

  • DNS resolution problems, where the system can’t convert server names to IP addresses.
  • Misconfigured network settings leading to failed server connections.
  • Firewall or antivirus software blocking the communication with the update server.
  • Incorrectly configured proxy settings or VPN connections disrupting access to the server.

How to Diagnose 0x80072EE7

To clarify the cause behind this error, one should:
