Here is a update of the case. I review the information you provided above. It seems that the metadata have been corrupted. I found that the downloaded updates are all .exe files in the software distribution log in your environment:

However, the updates files are all .cab in my environment:

The .cab files are Binary update files which are used to be installed on the clients.

Please help to confirm the followings first:

1. Make sure that the Firewall is running on the WSUS server first.
2. Change all the Approved updates to Not Approved Please refer to the below picture:
   Filter out all the approved updates:
   

Change the Approved updates to Not Approved

3. Please consider running the wsusutil.exe reset command on the WSUS server to reset the metadata.
Open the CMD as an administrator and then navigate to wsusutil.exe tool. Last post the wsusutil.exe reset command to reset the metadata.
4. Please consider approving the needed updates again.

Hope the above will be helpful.

Regards,
Rita

Answer 2

no more endpoints available from the endpoint mapper

this occurs when some process that uses dynamics ports is called repeatedly and never completes. It consumes all the dynamic ports

netstat -aon
should show this. As a work around try rebooting.

No proxy in our environment. I already connected to the URL and it downloads some files. I have tried installing it two times but no clue!! No KB number is getting downloaded for some of them it shows 100% or 75% or 25% but in the folder it does not show any content(shows zero mb). Also now it shows error 10032 event code.

config wizard did not resolve it. Approving the updates on downstream server did not resolved it and approving other updates also did not resolved it. Actually it shows that some updates are downloaded 100% abd some are 65% and 25% but if you ho to downloaded location it shows zero bytes means nothing is downloaded.
