I’m using the Cloudflare enterprise plan. certificate for my website will expire on 24-Oct-2023. I use Custom Modern certificate from third-party CA as Digicert. on the Cloudflare SSL/TLS encryption mode I’m using full(strict) mode. When I renew the new certificate on Cloudflare it require to import the new CA on backend server or just import only Cloudflare site. Please advise me.
