Remote PowerShell : Error 307 - windows

Question

On a Widnows 7 PC, I have an error 307 when I run the Invoke-Command or Enter-PSSession in PowerShell. I have the two computers in the trusted zone. When I run the same command on a Windows 8.1 or Windows Server 2012 R2, I don't have the error and the command works perfectly. The target runs Windows Server 2012 R2.
They both run PowerShell v4.0 (for Widnows 7, I upgraded according to MS : https://www.microsoft.com/en-us/download/details.aspx?id=40855).
For Windows 7 :
PS C:\> $PSVersionTable

For Windows 8.1 or Windows Server 2012 R2 :
PS C:\> $PSVersionTable

PSRemotingProtocolVersion 2.2
PS C:\> Enter-PSSession -ComputerName 127.0.0.1
[127.0.0.1]: PS C:>
Moreover, when I test the connexion with Test-WSMan, I get a HTTP error 12152. And the two machines ping the other.
Have you an idea for a possible solution ?
ps : the exact English message when run Invoke-Command :
