I'm afraid I don't think this suggestion will work in your case, but probably worth a try anyway ...

Sometimes ADE gets its registration/activation confused and in a semi-authorized state.

Unfortunately, it often then gives misleading error messages about what is wrong.

Try completely removing any authorization using ctrl-shift-D to ADE (cmd-shift-D if on Mac).

Restart ADE, and then reauthorize with your Adobe ID.

It sounds plausible, but sadly didn't help. Nevertheless thank you for the try.

I'm having the same problem.

ETA: Try using ADE 1.7 (you can find it here). It worked for me.

Preface: I know this thread is old, but I'm replying here because it's the #1 Google hit for the error.

I was receiving this error across multiple devices AND accounts. The common thread turned out to be my very long passwords (I use keychain software instead of trying to remember/type them manually.) Once I reduced my password from my usual 100 chars to a more manageable 12, the issue cleared up immediately and I was able to log in.

Length of the password turned out to be the issues on my side as well. Thanks for sharing as it solved my problem.

Hey Adobe, why is this still an issue? Seriously since 2013 people have to sacrifice security to use this product! It's 2020 now and I faced this issue just now.

The solution was to have a shorter password, that shouldn't be a solution!
