First things first, the setup is currently up and running. but i would like to modify it to use a reverse proxy through my personal domain.
Currently, i’m using an old pc with Truenas and a jail with jellyfin in it. i’m connecting to it with the free Fritz!Box VPN service.
but that’s stupid and slow. so i’ve bought a domain at godaddy.com. but i don’t understand the principle of whatever is managing the domain knowing the public IP-adress of my server. i’ve heard of Caddy, but it’s also running locally, so i don’t understand how i connect the pc to the domain.
if anyone could simplify this down for me, it’d be very helpful.
i may have figured something out, godaddy doesn’t support ddns, but you can change the ip of an A record via the API. and i have found a program that runs under linux as a service that does exactly that. problem is, where in my nas do i run it? do i try to install it in truenas? or jellyfin? or do i create a new jail with the sole purpose of running said program?

I suspect you can have GoDaddy use a CNAME record which points to a DDNS entry (which has an A record). I have done that with different services before.
Definitely ditch godaddy asap they are one of the worst companies to deal with.
I suggest https://njal.la/
It should work from just about anywhere in your network. Most of those DDNS clients end up using an external IP lookup service to get their public address and then send that reply to home base to update the record.
