I have a Jellyfin instance on my local server which I forward to the public web via a cloudflare tunnel. I'm not sure how secure it is, and I keep getting random requests from all over the world. It's my first experience maintaining something on a public domain so I may be worrying about something obvious, but some advice would still be appreciated.
Any time I've ever had a server of any kind connected to the net it's gotten endless 'doorknob turning' from bots scanning for stuff. At the very least, bots trying ssh passwords on common accounts.
I don't have any specific jellyfin advice, but random attempts from all over is pretty usual on the net these days.
