Cloudflare Origin through haproxy

I have an issue with using Zanzito with my setup. As a note, this works if I use the OwnTracks app on my device but does not work with Zanzito.

I am using Cloudflare for my DNS with HTTP Proxy (CDN) enabled. The traffic should flow as follows, Cloudflare:443 > haproxy:443 > mosquitto:1883 (non-tls)

The logs in Zanzito aren’t useful because all I see is either “MqttException” or “ Trust anchor for certification path not found.”

Still having no luck.
