Unable to upload podcast from Podbean to Itunes
Each time I enter my RSS feed into Itunes Connect, I receive the following error message
Podcast artwork must be between 1400 x 1400 and 3000 x 3000 pixels, JPG or PNG, in RGB color space, and hosted on a server that allows HTTP head requests.
I've checked my artwork over and over again and its within the limitations, and 228,868 bytes (229 KB on disk)
This is the specifics of the photo 228,868 bytes (229 KB on disk) - Can someone please help me? Here is my podbean link - https://citizenoftheworld.podbean.com/
Thank you in advance
