Image Validation Failing

I’m trying to validate this feed: https://newlifecanal.com/feed/podcast

And I keep getting an error on the itunes:image tag. The image is under 200kb, with a pixel size that is within the correct parameters. Here’s the image: https://newlifecanal.com/wp-content/uploads/sites/65/2022/03/Logo-scaled.jpg

Also, we are on a multisite network, with domain mapping. I think this is why my feed stylesheet doesn’t load. I have a ticket in with my host to help me sort that out as well. Not sure if that is somehow related.
