If you are unable to connect to your EC2 instance using SSH, there could be several reasons why this is happening. Here are a few troubleshooting steps you can take:

Check the Security Group: Make sure that the Security Group associated with your EC2 instance allows incoming SSH traffic from your IP address. To check this, go to the EC2 console, select your instance, and look at the Security Groups tab in the details pane. Verify that the inbound rules allow SSH traffic from your IP address.

Check the Network ACLs: If you are using Network ACLs, verify that the rules allow incoming SSH traffic from your IP address.

Verify the Instance Connect: Verify that you have the EC2 Instance Connect client installed on your local machine. If you do not have it installed, you can download it from the AWS website.

Check Instance Connectivity Status: Check the instance connectivity status in the EC2 console to ensure that the instance is running and has not been stopped or terminated. Also, make sure that the instance is in the correct subnet and that the subnet has internet connectivity.

Check the SSH key: Verify that you are using the correct SSH key to connect to the instance. If you have lost the private key, you will need to create a new one and associate it with the instance.

Try a different method: Try connecting to the instance using a different method, such as Session Manager or the EC2 serial console. If you are able to connect using a different method, you can troubleshoot further to identify the issue with SSH.

If you have tried these steps and are still unable to connect to your EC2 instance, you may need to contact AWS support for further assistance.

  • We already follow above steps. Also we did contacted to AWS support but the result still the same since AWS support asked us to follow the tutorial which lead to the same result. Thanks.
