bad signature because OCSP stapling not activated in the nginx config file

Most browsers currently have the stapling check set to true

e.g. Firefox/Chrome security.ssl.enable_ocsp_stapling = true

As a result, even if the certificate is valid, the browser still throws "SEC_ERROR_OCSP_BAD_SIGNATURE".

cause : stapling is not uncommented in the nginx config file when the certificate is configured.

ssl_stapling on;
ssl_stapling_verify on;
