How to check proxy connection in PowerShell?

The PowerShell command Test-NetConnection or the NETSH command Show-NetConnection can be used to check if a proxy is required in a current network session.

Get-NetConnection doesn't seem to work. The command is not valid on this system. The cmdlet Get-NetConnection has failed. You are using PowerShell on a remote computer. Run the command and try again.

A proxy is needed for the command to function correctly, and also to prevent an incorrect connection type (HTTP vs. SOCKS) from being detected. For example, if you are accessing a web server with HTTP via a proxy but without a proxy configuration on the local computer, the command will return an error since it can't determine if the connection type is HTTP or SOCKS.

If you have never seen a The cmdlet Get-NetConnection has failed error message before, check out some of the common errors listed here. If you still aren't seeing any helpful advice after running through the list, let me know and I'll take a look.

The Test-NetConnection PowerShell command is really simple. It simply tests if the network connections are either TCP/IP or an internet connection type (WAN:NAT or LAN:NAT).

If you run the above command on a system where there are no proxy configurations installed, you should see a test result as shown below.
