How would you troubleshoot a situation where a user is unable to access a web application hosted on a private server through a bastion host in AWS?

Question

Accepted Answer

Troubleshoot user access issues to a web app via a bastion host in AWS by checking network, permissions, and configurations.

Verify the user's network connection and ensure they can reach the bastion host.
Check the security group settings for the bastion host to ensure inbound rules allow SSH access.
Confirm that the user has the correct SSH key and permissions to access the bastion host.
Ensure that the bastion host can connect to the private server by testing connectivity (e.g., using ping or telnet).
Review the private server's security group settings to ensure it allows traffic from the bastion host.
Check the web application logs for any errors that might indicate why access is failing.
Ensure that the web application is running and listening on the expected port.
