Azure ATP Sensor install failing (Updater Service do not start)
Actually, the solution in our case was to use Silent Installation (https://docs.microsoft.com/en-us/azure-advanced-threat-protection/atp-silent-installation#proxy-authentication) and provide the Proxy Information in the commandline.
Thank you all for helping and advising!!!
MicrosoftPhilippFoeckeler Effectively this error means it was blocked.
Is your proxy doing SSL inspection?
No - there is no SSL inspection on the proxy... and in the proxy logs no blocks for this server. Very strange.
Local Firewall is switched off. So for this SSL connection to localhost on port 444, i cannot see any reasons that this should be not possible.

PhilippFoeckeler , Any chance you can temporary bypass this proxy just to see if it resolves the issue?
At least for the error sample you published, the problem is going to the azure backend, not to localhost.EliOfek , First of all Thank you so much for the help so far!!
Unfortunately, we are still stuck at the same point - the system is sensitive and Risk and Security Team do not allow to connect directly to the internet, even if it's temporary..
What we tried in the meantime:
We enabled routing to another Proxy which is used by other Domain Controllers (where the ATP sensor could be installed without any problems).... Proxy can be used in the browser, proxy was set as system proxy.... same issue - no blocks whatsoever are visible at the proxy.
We disabled local endpoint protection for this server (Cisco AMP) during the install....same issue.
I think i will open a Premier Support Ticket so that a MS Engineer can have a look in a remote session on this server....
