Some information may be filled in incorrectly or missed. It is recommended to check again.

Signature verification error may be that you have omitted to fill in some information, or filled in irregularly or not as required. Of course, the platform's audit system sometimes has problems.

If you fill it out again after a few hours, it should be successful.
