event id 364 wsus server content file download failed reason http status 404 error

Interesting that it's only W11. Let's cover all the bases.

Check your permissions - even if you think they are fine - just double check.

Have you enabled UUP mimetypes?

Run a wsusutil reset

& "$env:ProgramFiles\Update Services\Tools\WsusUtil.exe" Reset

Leave your WSUS Server alone for a full 24 hours. There are no notifications of when this process is running or finished. The reset will verify that every update metadata row in the WSUS database corresponds to update files stored in the local update file storage location on your WSUS server. If update files are missing or have been corrupted, WSUS downloads the update files again.

Then, in 24 hours, check the File Status column and see if the issue still exists.

Hello,

Thank you for posting in Q&A forum.

HTTP status 404 error indicates that the requested resource was not found. This may mean that the WSUS server cannot find the requested update file. To solve this problem, you can try the following steps:

Check the network connection of the WSUS server to ensure that it can access the required update files.

Verify that the path configuration for the updated file is correct. You can check the settings and configuration of the WSUS server to ensure that the updated file path is correct and error free.

If the updated file does not exist or has been deleted, you can try downloading or retrieving the required updated file again.

Ensure that the WSUS server has sufficient storage space to store updated files.

I hope this information is helpful to you! If you have any other questions, please feel free to ask.

Best regards，

Jill Zhou
