POST requests are being received as GET requests

Not entirely. I send a HTTP POST request, which cloudflare redirected to HTTPS, but when it did so it also changed the POST to GET which is slightly weird.
And yeah you definently shouldnt redirect to HTTPS when trying to use HTTP :sweat_smile:
But i do think the restart is necessary, because when i changed the settings while the tunnel was open and i then send a request, i would always get Error 502 - Bad gateway. But it works after you quickly restart the tunnel.
