Feed is malformed and cannot be parsed. Please make sure that the feed is a vali

Ok so I am setting up Amazon AI plug in which should be simple LOL. I know a lot of people seem to be having issues but no resolution and I want to be complete in the information. First when I go to Alexa Skill Blueprint and start a blog still it give me the following error message:

Feed is malformed and cannot be parsed. Please make sure that the feed is a valid RSS format.

I have validated the url at https://www.feedvalidator.org and it is valid.

I do have audio files and people can listen on the website but when I go to apple connect it doesn’t see any of my audio files. Not sure if these too issues are related but thought I would be complete.

Also I have checked the S3 where the audio files are and they are there. so Not sure where there is an issue with that.
