vSphere 5.1 "The server committed a protocol violation"
I am connecting to an vCenter 5.1 instance running on ESXi 5.1 with vSphere Client 5.1 over a VPN.
When I attempt to connect over the secured port 7444 I get an error. I was prompted to accept the certificate prior to the error.
vSphere Client could not connect to "xxx.xxx.xxx.xxx". An unknown connection error occured. (The client received an invalid response from the server. (The Server committed a protocol violation. Section=ResponseStatusLine))
If I try to connect over port 81 I get an error about the traffic not being encrypted and throws an error stating "The server 'xxx.xxx.xxx.xxx' could not interpret the client's request. (The remote server returned an error: (404) Not Found.)
Call "ServiceInstance.RetrieveContent" for object "ServiceInstance" on Server "xxx.xxx.xxx.xxx" failed.
