Why can't generate a token after entering SN and password on the OpenWRT warranty-waiver website?

After entering the device SN and password "234" (using the default password), the token is still not generated.

If AP does not have a unique password on the belly label sticker, is not eligible to use https://warranty-waiver.zyxel.com/ to unlock the bootloader.

Unfortunately, you needs to find a way to unlock the bootloader of AP.
