Hi @Dony-Thomas_7156 ,
You can ignore these errors. ProGet doesn't process these requests (i.e. store the content); instead ProGet simply generates the appropriate hash of a maven artifact when you request .ext.md5, etc. It's dynamic, not a file system.
That said, I do know that later versions of ProGet will simply return a 200 so that it does'nt cause an error with Marvin. I recommend to upload to the latest ProGet 2024, and use the New Maven feeds.
Thanks,
Alana
