I was wondering if "2FAS" worked with the two-factor authentication or if it was just the ones that were listed. Because when I scan the qr code with 2FAS i get a code, but the code does not work.

You can install one of the other authenticator apps on your mobile device and compare the result.

Make sure the date/time/timezone on all devices is correct and is synced to a reliable internet service as the TOTP code is only valid for thirty seconds. You can try to enter the otpauth:// directly in the app instead of using the QR code.
