Before initiating the reseed process source server will try to establish a connection to the remote host on HTTP protocol using WS-Management, which was failing because all the Http traffic was going through the proxy server.
Host applications can use a PowerShell object to run commands that use WS-Management–based Windows PowerShell remoting to create a temporary or persistent connection to the remote computer. This includes establishing an interactive session with a single remote computer.
PowerShell remoting uses the HTTP protocol, it is affected by HTTP proxy settings. In enterprises that have proxy servers, users cannot access a Windows PowerShell remote computer directly.
