Website is stop working from Monday.

Since your websites are not responding, here are a few steps you can take to troubleshoot the issue:

1. You should ensure that the security groups and network ACLs associated with your EC2 instances allow inbound traffic on the ports your websites are using (typically port 443 for HTTPS).

2. You should double-check the SSL offload configuration on CloudHSM to ensure it's set up correctly and that the certificates are valid.

3. You should make sure that your EC2 instances are running and that there are no issues with their status checks.

4. You should check the logs of your web server (e.g., Apache, Nginx) for any errors that might indicate what's causing the issue.

5. You try to do a ping or traceroute to check the network connectivity to your EC2 instances.
