How to fix "HTTPConnectionPool(host='localhost', port=8000): Max retries exceeded with url: /api/public/v1/health (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x74ea7f424c50>: Failed to establish a new connection: [Errno 111] Connection refused'))" while trying to connect airbyte with airflow

The error message you're seeing indicates that the connection to Airbyte's API on port 8000 is being refused. This could be due to a few reasons: 1. Airbyte is not running: Ensure that the Airbyte server is up and running. You can check this by visiting

<http://localhost:8000>

in your browser. If Airbyte is not running, you will need to start it. 2. Incorrect port: If Airbyte is running on a different port, you will need to update the port in your Airflow configuration. The default port for Airbyte is 8000, but this can be changed in the

.env

file in your Airbyte directory. 3. Network issues: If you're running Airbyte and Airflow on different machines or in different network environments (like different Docker networks), there might be network restrictions preventing Airflow from reaching Airbyte. You'll need to ensure that network connectivity is properly set up. 4. SSH tunneling: If you're connecting to Airbyte over an SSH tunnel, make sure the tunnel is properly set up and that the port forwarding is correctly configured. Here's an example of how to set up an SSH tunnel for port 8000:

bash SSH_KEY=~/Downloads/dataline-key-airbyte.pem   ssh -i $SSH_KEY -L 8000:localhost:8000 -N -f ec2-user@$INSTANCE_IP

docker logs airbyte-server

in your terminal (Source: [Airbyte Forum Post](https://discuss.airbyte.io/t/2122)). If you're still having trouble, consider reaching out to the Airbyte community on their [discussion forum](https://discuss.airbyte.io/) or [GitHub](https://github.com/airbytehq/airbyte/issues) for more specific help.
