Ran into this error as well.

In my case the package was too large, 164 MB. So I had to set higher values:

   <system.web>
     <!--The default size is 4096 kilobytes (4 MB). MaxValue is 2147483647 KB (2 TB)-->

     <httpRuntime maxRequestLength="2147483647" />
   </system.web>
   <system.webServer>
     <security>
       <requestFiltering>          
         <!--The default size is 30000000 bytes (28.6 MB). MaxValue is 4294967295 bytes (4 GB)-->

         <requestLimits maxAllowedContentLength="4294967295" />
       </requestFiltering>
     </security>
   </system.webServer>

Hope this helps!
