I'm having problems with Defender EASM data connector, it was working but not my connector says disconnected. I did the recommended changes on this link https://dori-uw-1.kuma-moon.com/en-us/azure/external-attack-surface-management/data-connections but still it's not working. Any help will be appreciated.

    Hi @Dr. Emmanuel Msengi, PhD I hope you are doing well,

    Thanks for reaching out Microsoft Q&A

    I understand you're having trouble with the Microsoft Defender for External Attack Surface Management (EASM) data connector.

    Sometimes a full reset helps:

    1. In Sentinel, remove the connector.
    2. Wait 10 minutes.
    3. Re-add it using the instructions in the official doc (including reauth if needed).

    you can follow this troubleshooting steps https://dori-uw-1.kuma-moon.com/en-us/defender-for-identity/troubleshooting-known-issues
