Blackbox - http probe not working but https does

Hi,
I’m after some assistance on what I’m hoping is most likely a simple fix to an issue I have with Blackbox http requests. I have installed Blackbox Exporter and Prometheus for the first time and have setup a few targets in prometheus.yml. One being https ://www.youtube.com which I get a success from as well as https ://prometheus.io.

However I am trying to probe the local host and another server on the same subnet using http but both return errors.

The errors I am seeing for both are

both local host and the remote server are on AWS and have the local firewalls turned off. I believe I have enabled the correct ports in the respective AWS security Groups

Any pointers would be greatly appreciated

thanks

p.s. added some spaces in the url’s to allow posting of links

This has been solved now.
