Error message for every prompt I've tryed

When I have seen this before, it seemed to be related to your authentication expiring in that instance. A shift reload in my experience has refreshed your authetication or asked you to log in again:

Glad to hear the problem is resolved.
If it worked fine via the CC desktop app, then there may have been a problem with authentication information, etc.
Next time you encounter such a problem, try deleting browser cookies and local storage first.

I've tryed other browser. I was using google chrome (my default browser) and changed to Firefox. It didn´t work, but then I entered the Firefly by the Creative Cloud Desktop and it worked! I still don´t know what happened, but now everything is fine again! Thank you a lot! 😉

I tried to your prompt and works fine.
Can you try another browser?
