Unable to add Steam Guard Mobile Authenticator (We are unable to add this account (code: 11))

[ID]

I tried to activate the Steam Guard Mobile Authenticator on my phone, but it just doesn't work. Whenever I press on the "Add authenticator" button, an error window just popped up and showed "We are unable to add this account (code: 11))". Has everyone encountered the same situation ? How can I fix it? And what actually is code 11 error?

Verify that your phone is compatible with the Steam Guard Mobile Authenticator: Make sure that your phone meets the requirements for the Steam Guard Mobile Authenticator. It requires an iOS or Android device with the latest version of the Steam app installed.

Ensure that your Steam account is in good standing: If your Steam account has any issues such as a ban, restriction, or dispute, you may not be able to add the Steam Guard Mobile Authenticator. Make sure that your account is in good standing before attempting to add the authenticator.

Wait a few hours and try again: Sometimes the Steam servers can be overloaded, and this can cause errors when adding the Steam Guard Mobile Authenticator. Try waiting a few hours and then attempting to add the authenticator again.
