When China Bank's new enterprise, Mobile Banking, signed a bank tax loan, the message "The ciphertext generated by CA authentication cannot be empty" appeared in the system. What should I do?

When China Bank's new enterprise mobile banking signed the 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. 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 version of corporate mobile banking of Bank of China is not the latest version. Please complete the version update before trying to sign the contract.
