How do I fix an SSL certificate expiration or Cloudflare 526 error on my custom domain?
Q: Why does my custom domain show “Certificate has expired”?#
A: This happens because Cloudflare’s proxy (the orange cloud) is enabled. When Cloudflare takes over HTTPS, the SSL certificate issued by Apidog is no longer used, so it appears as expired.

A: Turn off Enable HTTPS in the Custom Domain settings in Apidog. Cloudflare will handle HTTPS for you.
