Docker hub 2FA using OKTA verify - cant enable

Hi,
I’m trying to enable 2fa in my docker hub account but with no luck.
trying to use OKTA verify (on my android phone. okta verify version 6.8.1)
i manage to add a new account to okta verify and see a new code generated but when i insert the code to enable 2fa i get this:

any idea why is this happening ?

I’m using okta with other accounts so this is my default. did not try other auth apps.

thanks
Sivan
