What’s your go too (secure) method for casting over the internet with a Jellyfin server.

I’m wondering what to use and I’m pretty beginner at this

I see everyone in this thread recommending a VPN or reverse proxy for accessing Jellyfin from outside the LAN. While I generally agree, I don't see a realistic risk in exposing Jellyfin directly to the internet. ~~It supports HTTPS and certificates nowadays, so there’s no need for outside SSL termination anymore.~~ (See Edit 2)

In my setup, which I've been running for some time, I've port-forwarded only Jellyfin's HTTPS port to eliminate the possibility of someone ending up on pure HTTP and sending credentials unencrypted. I've also changed the Jellyfin's default port to a non-standard one to avoid basic port-scanning bots spamming login attempts. I fully understand that this falls into the security through obscurity category, but no harm in it either.

Anyone wanna yell at me for being an idiot and doing everything wrong? I'm genuinely curious, as the sentiment online seems to be that at least a reverse proxy is almost mandatory for this kind of setup, and I'm not entirely sure why.

Edit: Thank you everyone for your responses. While I don't agree with everything, the new insight is appreciated.

Edit 2: I've been informed that infact the support for HTTPS will be removed in a future version. From v10.11 release notes:

Deprecation Notice: Jellyfin’s internal handling of TLS/SSL certificates and configuration in the web server will be removed in a future version. No changes to the current system have been made in 10.11, however future versions will remove the current system and instead will provide advanced instructions to configure the Kestrel webserver directly for this relatively niche usecase. We strongly advise anyone using the current TLS options to use a Reverse Proxy for TLS termination instead if at all possible, as this provides a number of benefits

The issue is not encryption, it's the unauthenticated API. People can interact with your server without an account.

Specifically these issues: https://github.com/jellyfin/jellyfin/issues/5415

The big one is that video/audio playing endpoints can be used without authentication. However, you have to guess a UUID. If Jellyfin is using UUIDv4 (fully random), then this shouldn't be an issue; the search space is too big. However, many of the other types of UUIDs could hypothetically be enumerated through brute force. I'm not sure what Jellyfin uses for UUIDs.
