Advanced WSUS Troubleshooting for error 0x8024401f

Error 0x8024401f  may prevent you from installing updates from WSUS.
This error means the IIS had an internal server error while processing download request.

I didn't know that.

You may get something like this in your C:\Windows\WindowsUpdate.log :

So, first I checked it at the client's side if there was something in event log and then server's event log and got nothing.
Then I tried to browse my WSUS URL from Internet Explorer,
http://servername:8530/Content
and got error 500 Internal Server Error.
The error claimed that there were some duplicate MIME Type issues with IIS Configuration.
What does that mean?
So I Googled it, and then changed MIME Types that were added twice in IIS Settings.

On the error page, you can find those MIME Types which are repeatedly declared. In my case it was the ".psf application/octet-stream".
so, go to IIS Manager, Click WSUS Website features view, Select MIME Types, and delete the MIME Type from there.
Restart the website and check if you can Download updates now.
