I was getting this same message. I erased the authorization for my computer on digital editions and then reauthorized, seem to fix the problem.

Both ADE phone app and Windows software is showing the same error. No internet connection even though I am connected to the internet. And when I try to open my CSM file, it shows gibberish texts.
