Thank you for your help
I operated on the server with the newly installed panel, and Panel SSL seems to be working normally now.
However, this method does not work on another server that was upgraded from an older version to 7.0.29. After following your instructions (I tried the repair panel), the certificate I obtained is valid for 10 years.


Additionally, I noticed an additional bug. If you attempt this operation on the HTTP panel, you can apply for an SSL certificate and view its expiration date. Meanwhile, the Panel SSL will display as enabled. However, at this point, the panel has not actually enabled HTTPS. Only HTTP is accessible, and the panel's HTTPS is invalid.
