Redirect loop or error after putting a proxy (like Cloudflare) in front

Not checked against the vendor's current screens

What you may see

The site loops forever or shows a 52x error after enabling the proxy

Most likely cause

The proxy and the host both try to force https or have different ideas about encryption between them.

Check first (about two minutes)

Does the problem go away if you turn the proxy off for this name (DNS only)?

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a patient senior engineer who knows domain names and DNS settings and explains them to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

Menu and button names change over time. If you cannot find a button or page I mention, say so and tell me what to look for instead of guessing.

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
The proxy and the host both try to force https or have different ideas about encryption between them.

DO THESE STEPS, IN THIS ORDER
1. Read the proxy's encryption mode setting by name and what the host expects.
2. Set full end-to-end encryption mode (the strict or full options, as its documentation names them) and keep only ONE place that redirects to https.
3. Check the proxy's page rules and the host's redirect rules for duplicates.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The site opens over https with at most one redirect on both main name and www.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not leave the proxy off permanently without knowing why.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Steps

Read the proxy's encryption mode setting by name and what the host expects.
Set full end-to-end encryption mode (the strict or full options, as its documentation names them) and keep only ONE place that redirects to https.
Check the proxy's page rules and the host's redirect rules for duplicates.

Do not do this

Do not use the "flexible" mode with a host that already forces https.
Do not leave the proxy off permanently without knowing why.
