When China Bank's new enterprise, Mobile Banking, signed a silver tax loan, the system showed that "the ciphertext generated by CA authentication cannot be empty". How to solve it?

When China Bank's new enterprise, Mobile Banking, signed a silver tax loan, there was a prompt that the ciphertext generated by CA authentication could not be empty, probably because the authentication method you chose was SMS ordering. Please try to use the authentication method of dynamic password+SMS verification code or mobile phone shield+SMS verification code. It may also be because the new corporate mobile banking version of Bank of China is not the latest version. Please complete the version update before trying to sign the contract.
