I have checked previous posts and my ports are open on 443.
Ultimately trying to transfer files in our DMZ but it doesn't work when testing to Internal servers as well

You must also open port 902 between your station and the ESXi node where the VM is running.
From the Copy-VMGuestFile help page.

You must have access to the ESX that hosts the virtual machine over TCP port 902.

Brilliant. That's worked straight away.

Thanks for the quick reply.

The reason for the error is the same, but both 443 and 902 ports are open. Is there any possible reason

Does adding the Verbose switch give any more information?
