Welcome to the improptu guide for setting up Owncast with SSL certs on RunTipi.
The usual method of exposing Tipi apps though Cloudflare Zero Trust will not work with Owncast because it uses RTMP (a protocol for sending stream input), which is not supported as a service :(
(If I'm incorrect, let me know! Will defintely amend this guide and the RunTipi App Store Listing.)
