Kentico 8.1 MultiFileUploader.ashx 404 Error

The Issue

When I try to upload a file to the Media Library. It does not upload and the UI does not produce any errors. Looking into the console I see two requests. One creates the temporary folder in the temp location while the other gets a 404 not found error.

Any ideas as to what is going on here ?

Here are some screenshots of the 2 requests.

In the past there were usually two causes. One was large file upload, where you need to adjust the limits as describe din this KB article. Or, second cause was that the HTTPS/SSL was offloaded before the actual web server where Kentico is running, which lead to mixed content errors and 404. In this case you need to implement the SSL accelerator.
