What does this error mean?

Thanks for reaching out, Dileep. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

This is the error: aiohttp.client_exceptions.ConnectionTimeoutError: Connection timeout to host

The error

aiohttp.client_exceptions.ConnectionTimeoutError: Connection timeout to host

means that a network connection attempt to a remote server has timed out before any data could be exchanged. This is a low-level networking issue that occurs during the initial connection to the target host, and it generally indicates one of the following: • Network connectivity problems between your client and the server • The server is down or not responding • Firewall or network restrictions are blocking the connection • The host URL or port is incorrect • Timeout settings may be too low for your network conditions Recommended troubleshooting steps are: • Verify that the target host is reachable and running • Check your network and firewall settings • Confirm the server address, port, and API keys • Consider increasing connection timeout values if your network is slow • Check if a proxy is required in your environment This error is generally retryable after fixing the underlying connection issue. If you can provide more details about your setup—such as which LiveKit component you are connecting to, any relevant configuration, or logs—I can offer more targeted troubleshooting steps.
