In the early morning of 12AM Malaysia Time today, my server suddenly unreachable with SSL error. I had setup SSL/TLS encryption mode with Full (Strict) and uploaded Godaddy Wildcard SSL last year, and this SSL is valid until 2025.
However, this setup was missing from my account and it fallback to Let’s Encrypt generated by Cloudflare, and this SSL has conflict with the Godaddy Wildcard SSL I setup in my server like below
So my temporary solution is to switch to SSL/TLS encryption mode with Full mode so that user can use SSL from my server directly.
Now I want to upload again Godaddy Wildcard SSL to Edge Certificates page. However, it still showed SSL error after I switched to SSL/TLS encryption mode with Full (Strict). I re-check again my setup, it showed that my Certificate Authority is DigiCert. I just checked that DigiCert update · Cloudflare SSL/TLS docs mentioned Cloudflare will stop using DigiCert in the future start on 18th October 2023.
So anyone know obsolete DigiCert in Cloudflare will impact custom SSL purchased from Godaddy?
How should I solve this issue by remove DigiCert (Currently there is no setting to choose Certificate Authority when upload custom SSL)?
