This was happening for me because:
1. My IIS web application's advanced settings indicated "http,https" in "Enabled Protocols".
2. The "Default Web Site"'s "Site Bindings" did not have an https binding type.

And in order to resolve the issue, I had to do one of the following:
1. Remove "https" from the "Enabled Protocols" of my IIS web application's advanced settings.
2. Add the "https" binding type to the "Default Web Site"'s "Site Bindings".

Check your config file. You probably have two entries that have the same name, same contract, or some other duplication.
