ERR_TOO_MANY_REDIRECTS
The page redirects in a loop
Seen in Chrome, Edge (Firefox: "The page isn't redirecting properly")
Each response sends the browser somewhere that sends it back again.
Common causes
- A CDN in "Flexible" SSL mode talks HTTP to an origin that redirects to HTTPS.
- Conflicting www ↔ apex or HTTP ↔ HTTPS rules in two places (app and server).
- A cookie or session redirect that never completes.
How to fix it
- With Cloudflare, use "Full (strict)" SSL mode so the origin sees HTTPS.
- Keep one canonical redirect rule in one place.
- Follow the chain hop by hop to see where it loops.
