The sensor is blocked from communicating with the azure backend.
Do you need a proxy to get there?
Did you install the sensor in silent mode with proxy parameters?
by any chance is SSL inspection taking place ?
Any FW config that will block the process from communicating out?

I tried the silent mode but without the proxy parameters , i don't know how to go about that part.
by any chance is SSL inspection taking place ?
How should i check this?

See here:https://docs.microsoft.com/en-us/defender-for-identity/silent-installation#proxy-authentication
Reinstall with proxy params.
if it still fails, check with your proxy managers if they use SSL inspection.

You just need to add the 3 proxy params in the table to the standatd params after the last acccess key param and you should be fine.
You need to reinstall, you can't "update" and existing installation with proxy...- hemdan875Feb 15, 2021Copper Contributorthanks...Let me try that right now..
