Can't connect to Hyper-V server

Question

I've got two computers, one server running Windows Server 20H2, and a client using Windows 10 Pro. I've installed Hyper-V on the server and want to connect to the Hyper-V server using Hyper-V Manager on the client.

According to several guides/blogs/docs/etc I found online the following steps should be enough:

The steps I've done so far on server

1. PS> Install-WindowsFeature -Name Hyper-V -IncludeManagementTools -Restart
2. PS> Enable-PSRemoting
3. PS> Enable-WSManCredSSP -Role server

On the client:

1. Add entry in hosts file 192.168.0.2 my-server.internal.my-domain.com with IP of the server
2. PS> Enable-WSManCredSSP -Role Client -DelegateComputer "my-server.internal.my-domain.com"
3. PS> Set-Item WSMan:\localhost\Client\TrustedHosts "my-server.internal.my-domain.com" -Force
4. PS> cmdkey /add:my-server.internal.my-domain.com /user:Administrator /pass:<password>
5. Enabled Allow delegating fresh credentials with NTLM-only server authentication group policy and added wsman/my-server.internal.my-domain.com to the server list

After doing all this I still get the following error dialog:

Some things to note:

• Running powershell remote works fine (e.g. Enter-PSSession -ComputerName my-server.internal.my-domain.com), so authentication with WinRM seems to be working
• I've also tried opening port 5985 manually in the firewall on both client and server

Answer 1

I finally got it working, to solve it I needed to enabled WinRM correctly on the client by:

1. Open Local Group Policy manager on PC (gpedit.msc)
2. Go to Computer Configuration -> Administrative Templates -> Windows Components -> Windows Remote Management (WinRM) -> WinRM Client
3. Enable Trust the remote machine and add the hostname, or as I did for testing enable all by using *
4. I also enabled the policies Allow Basic authentication, Allow CredSSP authentication, and Allow unencrypted traffic here

Then when connecting in Hyper-V manager I had to use the computer name of the server, not the dns name.
