Connect to ESX - SSL Execption: Unexpected EOF

I'm trying to convert a running linux vm to a vmware workstation vm.

I found out that i need a ESX Host. I installed a ESX Server.

While trying to connect to the ESX Host (from the VMware Converter)  at the Step Target System (VMware Infrastructure-Server) I get an "SSL Exception: Unexpected EOF" error.

I tried already disableing SSL for the converter worker process.

Is there another way to convert a running linux vm to a vmware workstation vm?

If not, how can i fix the SSL error?
