Use your own domain instead

Under the web address, click Use my own domain instead, type a domain or subdomain you own, and click Set up my domain. Reelhost sets up Jellyfin and HTTPS on this computer, then lists the two steps that are yours, with your values filled in: forward TCP ports 80 and 443 on your router to this computer, and add a DNS A record for the domain that points at your home's internet address. Keeping that record current when your address changes is up to you.
