Defender Cloud Service URLs are not resolvable
When using the MDE Client Analyzer, Defender is not able not connect to the following URLs:
- https://edr-neu-eu.endpoint.security.microsoft.com/edr/commands/test
- https://mdav-eu.endpoint.security.microsoft.com/mdav/wdcp.svc/heartbeat
- https://edr-weu-eu.endpoint.security.microsoft.com/edr/commands/test
The FQDNs are not resolvable. This error is not exclusive on our network.
Is there something wrong with the DNS entries at Microsoft ?
