Troubleshooting Redis Connection Issues in the AWS Environment

When a Redis instance in an AWS environment is experiencing connection issues, ensure the Security Group (SG) configuration allows VPN traffic to port 6379. Then, using the nc command, verify the Redis instance's accessibility.

If you encounter local DNS resolution problems, consider changing your DNS provider or connecting directly using the Redis instance's IP address, which can be obtained via the dig command.

For persistent DNS issues, resetting your router or using external DNS query tools may help. If other troubleshooting steps fail, exploring AWS network interfaces can offer additional insights.
