Not found because of proxy error: Error: read ECONNRESET

[de-it-projects]

whilest using your plugin for github repo for the proxy server and calling to it with a link to get around the CORS-POLICY-ERROR we find ourself with this error:
Not found because of proxy error: Error: read ECONNRESET

the URL we're trying to use: (this is without using https:// in front of the 2nd link)
https://proxy.[domain].nl/[encoded_url]

if we use https:// on both we get the error:
The URL is invalid: two slashes are needed after the http(s):.

whilest using the Demo version of your plugin (https://cors-anywhere.herokuapp.com/corsdemo) we can send a request with "https://" in front of it and without.
If we remove this whilest using our own proxy we can do a POST but with the request to get results from our POST we get the error shown above

You need to configure your server to preserve the original request URL. See my reply to #417 including the links at https://github.com/Rob--W/cors-anywhere/issues/417#issuecomment-1094308715.
