Airbyte

Hi, I followed the steps by the documentation and am pretty sure everything is set, and I could open <http://localhost.8000> yesterday and this morning. But it is not working since then, and keeping receiving the error 'channel 2: open failed: connect failed: Connection refused'. I googled and troubleshooted it , still failed.<https://docs.airbyte.com/deploying-airbyte/on-aws-ec2/>

I'm sorry to hear that you're having trouble with Airbyte. Based on the information provided, it seems like you might be experiencing a connection issue. In a similar case, a user faced connection issues after restarting their VM on GCP [source](<https://airbytehq.slack.com/archives/C021JANJ6TY/p1668122294159259>). The issue was resolved by restarting all the containers after restarting the VM.  You can try restarting all the containers and see if that resolves the issue. If the problem persists, please provide more information about your deployment, such as the OS or cloud platform you're using, so we can better assist you.
