MQTT connection over Proxied DNS

Hello,

I have a Mosquitto server (v2.0.14) running on Ubuntu (v20.04) server in AWS, I use MQTT.js client to connect to the broker server via port 8443; the client can connect to the broker only if the proxy status is DNS only (gray icon), if I use the proxied state (orange icon) the client cannot connect to the server.

can you pls let me know what is it I’m missing here?

Looking forward to your support!

You are not going to be able to proxy MQTT with an :orange: record unless you look into Spectrum. Cloudflare supports ports 8443 but only for HTTPS connections(list of ports).
