Cannot connect to server using Enter-PSSession

I’m quite new to PowerShell and am trying to write a script that connects to our web server from our db server and pulls a file across. Unfortunately I’m hitting hurdles straight out of the gate with the following error when trying to use the Enter-PSSession cmdlet:

I can confirm that PowerShell on the web server is set up and ready to receive connections:

I am at a loss as to what to check now. Any help would be greatly appreciated.

What results do you get if you use the server name instead of the IP address?

Thanks for your reply - I think this issue can be ignored for now, I’ve spoken to our sysadmin who’s mentioned there’s a larger issue preventing the connection. I’ll try again once this is resolved.

Do you have the same error while trying to enter PSsession locally on the server?
