What does it mean ?

ERROR_WSMAN_CONNECTIONSTR_INVALID  
The WinRM client cannot process the request. The connection string should be of the form [<transport>://]<host>[:<port>][/<suffix>] where transport is one of "http" or "https". Transport, port and suffix are optional. The host may be a hostname or an IP address. For IPv6 addresses, enclose the address in brackets - e.g. "http://[1::2]:80/wsman". Change the connection string and try the request again.
