If a user is behind an authentication proxy, the user provides the proxy credentials in the Creative Cloud App. On launching an Adobe application, a display box is displayed prompting the user to enter the proxy credentials (for authorization and licensing related calls) again. This happens although the user has provided them earlier.

Resolution

Provide credentials again and select Save in Keychain control.

Once the credentials are entered in the app and the user opts for remembering the credentials, it should not display a dialog box prompting to enter the proxy credentials again.
