ERR_SPDY_PROTOCOL_ERROR Ajax .net web api : <p>Running into a very strange error when trying to execute Ajax calls to a .NET Web Api hosted on IIS on Azure.  </p>

<p>I've got my SSL cert from let's encrypt, it's applied to the website properly.  When I try to execute an ajax call I get:</p>

<p><em>net::ERR_SPDY_PROTOCOL_ERROR</em></p>

<p>If Fiddler is open, all works properly.  With Fiddler closed, we get the error.  Regular old HTTP works just fine.</p>
