Cloudflare 526: The Redirect Loop Behind One Setting
Flexible gives you an infinite redirect. Full strict gives you a 526. The documentation says Full or higher, and higher is the one that breaks.
| Mode | Cloudflare to origin | What happens against an HTTPS-redirecting origin |
|---|---|---|
| Flexible | plain HTTP | Origin redirects to HTTPS, loop |
| Full | HTTPS, certificate not validated | Works |
| Full (strict) | HTTPS, certificate validated against a public CA | 526 if the origin certificate is internal |
