Connexion existante mais fermée par l'hôte distant

Good evening, I have a problem recently that I still can not solve.

When I want to launch a hots machine, I get the following error message:

Error creating machine: Error during driver creation: read tcp 127.0.0.2:51171->127.0.0.1:51170: wsarecv: An existing connection had to be closed by the remote host

Thank you for your reply . And I hope I have the solution here.

Sincerely Lefleo
