why do i get "access denied" on this ssh tunnel

The key file (key.pem) should have chmod 400 permissions

you need to set the right permission to the SSH key you are using like the

chmod +X  key.ppm or chmod +X  key.pub

or it's equivalent in windows

So ( for testing ) only http to http with no key , will not work ?

1. You can use password authentication for SSH tunnels, but you must ensure SSH server settings allow it.

2. Double-check security group rules and network settings.

3. Test by accessing the tunneled port and verify that the HTTP service is running and reachable.

4. If you’re testing an HTTP tunnel (HTTP traffic over SSH), make sure:

   HTTP Service: The HTTP service on the target private IP is running and accessible. Local Port Binding: The local port you are using for the tunnel (e.g., localhost:local_port) should be available and not blocked by local firewall rules.
