website down saying can not be reached

When encountering a "This site can't be reached" error for your website, there are several potential causes and solutions to consider:

1. Check your EC2 instance configuration:

• Ensure your EC2 instance is running in a public subnet.
• Verify that you're using the public IP address of your EC2 instance, not the private IP.
• Consider setting up an Elastic IP if you don't have a public IP address.

2. Review your security settings:

• Check the inbound rules of your EC2 security group to allow HTTP (port 80) and HTTPS (port 443) traffic.
• Verify the inbound and outbound rules in your subnet's Network Access Control List (NACL).

3. If using Route 53 for DNS:

• Confirm that your A record is set up correctly.
• Ensure your nameserver records are properly configured and aligned with the NS records in your Route 53 public hosted zone.
• Check the TTL (Time to Live) for your NS records, and consider lowering it temporarily if you've recently made changes.

4. For CloudFront distributions:

• Verify that your SSL/TLS certificate is properly set up and linked to your distribution.
• Check that your domain name is correctly configured in CloudFront.

5. Backend health:

• Ensure your web server (e.g., Apache) is running correctly on your EC2 instance.
• Check server logs for any errors or issues.

If you're still experiencing issues after verifying these points, you may need to investigate further by checking your application logs, testing connectivity directly to the server, or consulting AWS support for more specific troubleshooting steps.

Hello,

1. Check EC2 health status on console: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/viewing_status.html . If Instance check failed, maybe you could stop ec2 and start.

2.SSH EC2, check your application or service.
