:::tip
For WebSocket connections to work correctly, especially when your Open WebUI instance is accessed from a different domain, you must also configure the `CORS_ALLOW_ORIGIN` environment variable. This variable tells the server which origins are permitted to access its resources.
For example, if you access Open WebUI from `https://my-open-webui.com`, you should set:
```bash
CORS_ALLOW_ORIGIN="https://my-open-webui.com"
```
Forgetting to set this variable is a common cause of WebSocket connection issues. You can also provide a semicolon-separated list of origins.
