@Tom

Proxy settings are missing for SYSTEM.

Solved by set up the proxy for Local System account.
Download PsExec.exe.

Start a command shell (cmd.exe) with administrator privileges.

PsExec -i -s cmd.exe
This will open a new cmd.exe that is running under Local System authority. You may check this by executing "whoami" command into that new command shell which will return "nt authority\system"

Open the Internet Options with this command:

inetcpl.cpl
Go to “Connections” tab, click on “LAN settings”, and set up the “Proxy server” section with the relevant proxy address and port number.

(optional) If you need to Bypass proxy server for local addresses, tick the relevant checkbox.

(optional) If you need to specify exclusions, click “Advanced” and set up the “Exceptions” section accordingly, and click “OK”.

Click “OK”, and exit all open command shells.

Secteer agent is now communicating with the Secteer backend!

@Tom

Thanks for your answer and pointing to a direction to investigate and possible solution.

Also we will update the whitelisted servers in our Proxy server.

Kind regards,

Some of our Agents having issues communication with Secteer.

White listed in the Firewall/Proxy configuration.
