Cannot sign into Creative Cloud from Chromebook. Windows 11 works fine.

I am resurrecting this thread. Chromebooks are advertising Lightroom. I am using the same credentials on my Windows 11 PC as I am on the Chromebook (I use a password manager that works on both environments). Windows works. Chromebook fails. I'm just trying to sign onto Creative Cloud - not even entering Lightroom.

I sign in with my email address onto my Adobe Creative Cloud,

I attempt to verify my identity., *

I enter my password.

And I get "This site can't be reached."

I said I attempt to verify my identity.. "Use Adobe Account Access app to verify identity" makes my mobile phone to say accept or deny. I accept, of course. But the Chromebook never sees the response - so I resend the notification - and I can continue with my infinite loop. Instead, I used "an app to generate codes". I "Enter the authenticator code generated by the Adobe Account Access app.". At that point I am allowed to enter my password. And, then, I get "This site can't be reached" - as before.
