EC2 is running, but no connection.

Hello,

Thank you for your question, I understand that you currently unable to connect to your instance as it is failing status checks.

Please confirm whether it is failing:

Instance level checks = 1/2 this means that the issue is with OS level operations (AWS has no visibility)

System level checks = 2/2 this generally means that there is an issue with the underlying host hence (stop/start will be required)

To check why the instance is failing status checks you can use the console logs/instance screenshots, you can reference this link [1] for further troubleshooting:

To get console output

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
2. In the left navigation pane, choose Instances, and select the instance.
3. Choose Actions, Monitor and troubleshoot, Get console logs.

To get screenshot

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
2. In the left navigation pane, choose Instances, and select the instance.
3. Choose Actions, Monitor and troubleshoot, Get instance screenshot.

Once you have determined the cause for status check failure, you can reference this link [2] for common troubleshooting methods for 1/2 status checks.

Feel free to share console log and/or screenshot should you require further assistance with troubleshooting
