Fix · Sign-in and accounts

Login works on my computer but not on the live site

Blocks your work

What you may see

Sign-in loops back to the login page online

Most likely cause

The live site uses https, another domain and other settings: the allowed addresses, the cookie rules or the keys differ from the local setup.

Check first (about two minutes)

Compare the sign-in settings of local and live: site address, allowed redirect addresses, keys (names 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.

The exact error or what you see

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 careful senior engineer who knows sign-in, sessions and user accounts, 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.

THE PROBLEM
Login works on my computer but not on the live site

THE EXACT ERROR OR WHAT I SEE
[paste the exact error here]

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

MOST LIKELY CAUSE
The live site uses https, another domain and other settings: the allowed addresses, the cookie rules or the keys differ from the local setup.

DO THESE STEPS, IN THIS ORDER
1. Check the site address and allowed redirect list in the auth service for the live domain.
2. Check cookies in the live browser tab: set, secure, same domain, not blocked.
3. Check environment variables on the host for the auth service (names only) and redeploy.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- A new account can sign up, log in, refresh, and log out on the live site.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not turn off secure cookies.
- 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.
