Excuse the basic questions but I'm not having much luck web searching for answers. I have the server running on my laptop which is also where the content itself if and I have an android phone with the mobile client installed via f-droid.

I can't seem to cast to chromecast with Jellyfin from either the laptop itself, or the android client app. The client app lists streaming to chromecast specifically as one of it's features in the description on f-droid.

OK, i know how to. But it's a difficult one as english is not my first language.

Chromecast has some internal security. One of them require to have a valid HTTPS certificat on the website (your self hosted jellyfin instance) plus be able to resolving the DNS of the website (your self .....) through the DNS on Google.

Have fun....

The solution is to buy a domain, customizing the DNS to your internal ip (192.168.x.y). AND using a revers proxy like traefik to setup a certificat with let's encrypt.

It's hard but i made it so you will be able to do it too.

Edit : for more precision, i'm speaking about a situation meet and resolved few months ago.

I can't make any assumptions about the situation today with the latest dev in the jellyfin app, let alone with the possible differences between the google play version and fdroid.

Weird. I believe I can cast to mine while only accessing it through http and without my external domain.

Maybe not the same version of chromcast ? I can assure you that i spent a lot of time and effort to make it works and this solution wasn't invented by me. 😆

So, basically, the problem exist and this is a solution.

I juat tried casting from my phone (Android 14) to my Chromecast with GoogleTV.
Though my jellyfin has a public facing domain, it's hidden behind a proxy. ATM I only use http internally without whitelisting.
So I am fairly certain I am casting from a http source for whatever reason.
And I can assure you my chromecast is reported as a casted device. Jellyfin reports this string on the connected client page: "Google Cast Chromecast 3.0.0-"
