Common problems and solutions
Let's try to describe the issues that we have faced while working with Amazon Virtual Private Cloud (Amazon VPC):
- Problem statement 1: You have created an instance in a VPC, but you are not able to access the instance using SSH; you can't even ping the instance from your machine/laptop
- Solution: There are many reasons why you are not able to access the instance using SSH or not able to ping the AWS instance available in VPC
Let's discuss this one by one, as follows:
- If you are not able to access an instance created in a VPC, then just for verification, check whether you are using the correct public DNS and IPv4 public IP.
- Use the correct public DNS and IPv4 public IP in PuTTY in hostname or IP address field to access the instance.
- Another important thing you need to access an instance available in a VPC is the key pair that you selected while creating the instance. You must have access to the same access key.
- If you are using PuTTY, click on
Connection|SSH|Auth...
