Vcenter Discovery Error - error when accessing the SDK URL at https://servername/sdk

[Anand D]

Hi ,

I have been encountering an error while discovering one of my Vcenter. Below is the Error Message :

1. Cannot connect, status is SSH_PROTOCOL_FAILURE. Received server DISCONNECT message: DISCONNECT: code: 2, reason: Protocol error, description: Too many authentication failures

2. Unable to establish connection to https://10.199.104.100/sdk: java.rmi.RemoteException: Exception caught trying to invoke method RetrieveServiceContent; nested exception is:
java.net.SocketException: Connection reset

3. Timeout trying to read from https://10.199.104.100/sdk

I have checked for firewall blocks and server MTU and all are good. VmWare admin says its not a server issue and share me a KB from VMware which says /sdk will not be accessible as it is not an HTML link. 

I have also verified the credentials and it works fine accessing /mob but not /sdk.

VMware KB -- Informational: Expected error when accessing the SDK URL at https://servername/sdk (1003218) (vmware...

Please advise.

You may want to verify the credentials used for windows discovery. That was the issue in my case.
