Thank you very much

The link from support of httpheader.net says

This is usually an indication that either the IP you are on had a proxy server at one time, your IP is being probed to see if it contains a proxy server or someone just has their software miss configured. These can usually be ignored as they pose no direct threat.

Also the default API routing on your server side is not very well configured. It should be returning 404 if the page was not found on your server instead you are returning 200.

You can block all these requests if you want to.
