I still don't recommend putting jellyfin on the Internet. It's not designed for it. There are some API endpoints you can access without authentication, not to mention potential authentication bypass vulnerabilities.
5 minutes is also probably too frequent. Leases are usually significantly longer. You might hit a rate limit and get blocked.
Thanks for the tip! I’ll back the refresh rate off to be safe.
I’m not sure I entirely understand your concern about putting Jellyfin on the internet. A large part of my interest in selfhosting is being able host my own music library, my own cloud storage, etc, and access it as an alternative to Spotify or Google Drive. Doesn’t that inherently mean that they need to be on the internet, if I want to be able to access them when I’m away from home?
My goal has been to find a way to do that safely, but if that’s not possible, that’s good to know too, so I don’t keep trying to do the impossible.
Wireguard or tailscale are much better ways of accessing jellyfin from outside your network.
What if I want a bunch of people to be able to log into my library via Finamp?
Provide them with VPN access. If that's too much for them, then they don't get access. Tough. On the scale of security vs convenience, that's nothing.
If you really really want, you should at least see if you can put a WAF in front, and put the server itself somewhere it doesn't have access to the rest of your network (a DMZ) so that if and when it gets hacked, it doesn't compromise the entire network.
I highly recommend Tailscale, you can share machines/services with unlimited friends on the free tier, and all of the actual auth stuff is handled by someone who isn't me.
You use plex instead, or you accept the massive security vulnerabilities.
What vulnerabilities? Sure there are some but nothing massive that I have seen. Care to post them.
web endpoints with zero authentication lol
It's honestly just a matter of how much risk you are comfortable with for using jellyfin on the open internet.
(If i remember correctly:) The unauthenticated routes thing can only be used for streaming your content without a login (if you can guess the contents ids on your server I believe).
In my opinion, it's not worth the hassle of using a vpn because I don't think this risk is worth mitigating with one.
But everyone has their own personal risk assesment of course.
P.s. Easier than a VPN, at least for logging in other users, would be to use some type of proxy authentication like Authelia. I believe jellyfin has a plugin you can use. It can be complicated to setup, but it's an option. I believe it should protect all routes exposed by jellyfin so that solves the unauthenticated streaming issue. (I still dont think this is necessary but more choice for the risk-adverse!).

Yet everyone in here tells everyone to switch from Plex, which is designed for it, to jellyfin lol
I prefer security vulnerabilities I can manage to privacy ones I cannot.
What privacy vulnerabilities are you talking about exactly?
Only one of these software has lead to someone hacking into someone's computer.
You have no idea how many breaches jellyfin has been the cause of lol
