How to Reverse Proxy Jellyfin with Caddy on Docker (Beginner Friendly)

[TheDreadPirate]

This is why I love Caddy! You can totally forget about complicated 1networking stuff and just let Caddy/Docker handle it all with some application of dark magic.

Save yourself the headache and just lease a domain. Not sure if you can still get them for free, but it's only like $4/year to register a memorable domain. Personally I've been using Cloudflare (a bit more expensive, I think like $12/year) to manage my domain and DNS settings. The convenience as ultra-fast DNS propagation is totally worth it if you're homelab-ing. 

If you're hosting a sever at home it's in your best interest to get IPv6 set up. The huge advantage is that IPv6 restores end-to-end direct connections as was originally intended with the internet.

You get even quicker DNS propagation if your home router uses Cloudflare as the DNS provider.  At least for clients on your home network.

And Cloudflare has an API for updating your IP, so it is effectively like a DDNS service as well.

watched video but having issues reconciling to installing caddy in docker under synology DSM. I've got duckDNS done (but it's offline at the moment) but cannot seem to get the final configuration done under synology DSM 7.x

Just bumping this to again thank the OP and remind myself for the future to watch the video till the end and not forget to run NSSM in the process!

I spent the entire day trying to do this and followed the video to a Tee but my ports will not open on my router. I set up the port forwarding rules properly (and the Linux UFW ports) and disabled a whole bunch of stuff to make sure that wasn't it, but the ports will not open on portchecker. Do ISPs not allow these ports to open? I even tried alternative ports (8880, etc) and they wouldn't open either, as well as working with Copilot which had me run in circles for hours. At this point I feel like it would be easier to figure out Tailscale.

I used this video which I think is the same thing but for Linux. It's by the same guy.

EDIT: Figured it out. Had to call ISP to get open ports.
