Having issues with ADE on my Mac. When I try open an ebook download it says "Connection Error Detected: Digital Editions could not connect to the fulfillment server. Please make sure you are connected to the internet" I am definitely connected to the internet. I've tried uninstalling and reinstalling to no avail.... Any suggestions welcomed!!

I had the same issue since October. I couldn't download library books. Found out it was an expired Certificate Authority. Hope this helps you.

I tried so many different things based on all the "status quo" troubleshooting for this issue, and they did nothing to resolve it. Finally I came across your post, and it was the game changer! Thank you so much! ❤️

I had the same problem and after a week of trying everything the other threads suggested, I'm glad I found this one. I can borrow books from the library again. I was already thinking of buying a new Kobo. Thank you! You're the only one who gave this solution.
