Webhook and reverse proxy?

Hi. I’ve been able to successfully setup a webhook and test it. However, I’m trying to send the webhook to my smarthome server (homeseer) via a reverse proxy and I don’t seem to be getting the response. I setup the receiving URL in the webhook as my domain and alias: example: rachio.myDomain.com. I then set that up as an incoming request to my reverse proxy server via port 443 then redirect it to my smarthome server on it’s IP address: example: (I picked port 9300 as a random unused port). I then use in mcsMQTT plugin as a TCP webhook but I’m not getting any data. Ideas? Thanks!

I was able to figure this out. I just needed to add a custom header to the reverse proxy (in Synology). See attached.
