Trying to develop a web-based app connecting to an existing production vCenter setup. According to the administration screens, the vSphere Web API's url is https://servername/sdk
When I try to access the API's wsdl at
(and all kinds of games with port number that shouldn't work and, in fact, don't)
I get 404. Always.
Any suggestions how to connect to the API?
Note that all existing machines and services are running just fine: Web Client connects and shows data, Power CLI gets all kinds of good stuff when using that to query the server, etc.
