# Troubleshooting

> Fix common browser SDK setup issues.

## No sessions arriving

Almost always an origin mismatch. Open your browser's network tab and look for a failed request to `/v1/ingest`. A CORS error means the origin your app is served from is not in Hinto's allowed list. Add it under Settings, API keys. Remember that `http://localhost:3000` and `http://127.0.0.1:3000` are different origins, as are different ports.

## Sessions arriving but not attached to anyone

`identify` is missing, or it runs before your user object is loaded. Call it after sign-in completes, and again after a user switch. See [Identify users](/identify).

## A 401 from the ingest endpoint

The key is wrong, was revoked, or belongs to a different environment. Mint a fresh one under Settings, API keys.

## A 403 from the ingest endpoint

The key exists but lacks session-ingest permission. Mint a key with the session capture purpose rather than the MCP handoff purpose.
