I have downloaded ebook into my computer and able to read. Now I am trying to access same book from my iphone and ipad but not able to do. I am able to view the book names in my library in phone and ipad but when I try to open I am getting "Connection Error Detected"-"Digital Editions Could not connect to the fulfillment server. Please make sure you are connected to the internet.".
I was able to read book from iphone a month back but now I am trying with different ebook and getting this issue.
I cobbled a solution together from various answers here.
