Missing or invalid session cookie / bearer token \n • The client never receives (or immediately loses) the cookie/token that proves it is logged in. \n • Every subsequent request therefore returns 401, so the client loops.\n\n2. Same-site / secure cookie mis-configuration \n • If the IdP sets the session cookie without `SameSite=None; Secure`, modern browsers will drop or restrict it when the app is embedded in an iframe or served over HTTP, again producing 401s.\n\n3. Clock skew between IdP and application server \n • Tokens or assertions are issued with a `notBefore`/`exp` that the backend considers “in the future” or “expired,” so validation fails with 401.\n\n4. Redirect URI / callback mismatch \n • The IdP issues an auth code or SAML response for `https://app.example.com/callback`, but the client is posting to a slightly different origin or port, so the backend cannot map the response to a valid session and returns 401.\n\n5. CORS pre-flight failures on token exchange endpoints \n • The browser blocks the token-exchange call; the client never obtains the access token, so every API call is 401.\n\n6. Reverse-proxy stripping auth headers \n • An nginx/Apache layer in front of the app removes `Authorization` or cookie headers before they reach the backend, so the app always sees an anonymous request.\n\nHow to confirm and break the loop\n\n1. Open DevTools → Network, filter by the protected endpoint, and look at the request headers/cookies on the failing 401. \n • Is the session cookie present? Is the `Authorization: Bearer …` header intact? \n • Check the response for any `WWW-Authenticate` challenge that might hint at the exact failure.\n\n2. In the Application (or Storage) tab, inspect cookies for the domain. \n • Verify `HttpOnly`, `Secure`, `SameSite`, and `Path`. \n • If the cookie is missing or restricted, adjust the IdP configuration or the application’s cookie serializer.\n\n3. Compare system clocks on IdP and app server (`date`). \n • If they differ by more than a few seconds, sync them with NTP.\n\n4. Verify the registered redirect URI(s) in the IdP exactly match what the client sends (including protocol, host, port, and trailing slash).\n\n5. Temporarily bypass the reverse proxy or add an explicit `proxy_set_header Authorization $http_authorization;` (nginx) to ensure headers are forwarded.\n\n6. Add client-side logging right before the auth redirect: \n ```js\n console.log('Auth state:', getAuthState(), 'token:', getToken());\n ``` \n This will show whether the client thinks it is authenticated when it actually is not.\n\nOnce the cookie/header is delivered intact and the token/assertion validates, the 401s stop and the oscillation ends.", "error": null, "prompt_tokens": 284, "completion_tokens": 658, "sec": 7.392460823059082, "cost": 0.002, "web_tools": [], "n_calls": 1, "nudged": false } ]
