Connection error

A connection error in the logs almost always means a device, service, or network on your side is unreachable, not a bug in Home Assistant. For example:

ConnectionRefusedError: [Errno 111] Connection refused

A few things to check:

  • The device or service that the integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] talks to is powered on and reachable on your network.
  • Your network is healthy. Routers, DNS, or DHCP problems can take services offline.
  • For cloud services, check the provider’s status page. The internet service may be temporarily down.

If the error mentions a specific integration, the integration page often has a troubleshooting section with more focused advice.
