Hi @jacky_vwindesk

your domain name is required to check that. Or use “check your website” to test your site and share the link.

Sounds that you use OCSP must staple - hit F5.

Thank you, I set ssl_stapling in nginx_conf, and it works now

If you have created a certificate with "OCSP - must staple", it's required that your server has a working "OCSP Stapling".

First is a certificate property, second a feature of your webserver.
