If Alibaba real-name authentication fails, you can solve the problem in the following ways.

First, check whether the ID number and name submitted are consistent with the actual information.

Second, you can contact Alibaba customer service to understand the specific reasons and provide relevant supporting materials so that you can resubmit the authentication.

Finally, if the authentication still fails, you can consider using other credible platforms or payment methods to conduct transactions. In any case, it is very important to ensure the authenticity and accuracy of personal information.
