Getting error message for podcast artwork specifications

Hi there

Please try this

• Check the Exact Dimensions: Your image must be square (an exact 1:1 ratio) and between 1400 x 1400 pixels and 3000 x 3000 pixels (3000 x 3000 is strongly recommended).
• Switch to JPG or Save as PNG without Transparency: Apple Podcasts does not support alpha channels or transparency in show covers. If you are using a PNG with transparency, export it as a solid JPG or a PNG with the alpha channel removed. 
• Convert to RGB Color Space: The image must be saved in the RGB color space (CMYK is not supported). Saving or exporting your file as a JPG usually forces it into RGB mode. 
• Reduce File Size: Even if dimensions are correct, a massive file size can trigger validation issues. Try keeping your file under 500 KB (or around 300 KB
• Verify HTTP HEAD Requests / Hosting: Sometimes this specific error is a generic fallback message when the crawler fails to pull the image from your web server or RSS feed. If you host the image yourself, make sure your server permits HTTP HEAD requests and includes a Last Modified date header.[
• Test Your RSS Feed: Run your feed through a validator  to pinpoint whether the issue is the image file itself or your hosting server. 
• Apple Podcasts Connect Workaround: If you are managing your show directly in Apple Podcasts Connect and the RSS image keeps failing, you can temporarily remove the RSS feed link in your show details, manually upload your 3000 x 3000 artwork, save it, and then re-add your RSS feed
