Hi everyone,

Edit2: I bought a domain (1,50€ p.m.) from a European service which also offers dynDNS functionality. Just needed to adjust my NGINX config and generated new SSL-certificates via Certbot. I also built a script that only issues the update URL if the actually IP has changed. The system has been running flawlessy now for a couple of days already. No outages or any other connection issues. Learning: even though the dynDNS functionality should work stable in theory (since there is not much going on), the dynDNS service provider actually plays a big role in terms of reliability.

a couple of friends and I have a Jellyfin server running which is exposed to the internet via a reverse-proxy and https by using a free dynDNS provider.

The setup is working fine besides the dynDNS provider. We constantly face connection issues, making the dynamic DNS functionality very unreliable.

So I started looking into possible solutions and one particular would be to buy an own domain which would only cost a few bucks each month. With this I could keep the current setup and would just need to change the domain (and possibly the SSL certificate). I found a provider over which I could buy (rent?) a domain and which also provides dynDNS functionality. But I am not too sure if I understood this correctly:

• if I have an own domain, why would I need the additional dynDNS functionality? I would guess that I would just continue updating your server's IP address to the domain name like we are doing now
• can the provider over which I rent the domain with servers in my country actually see what our traffic is? Especially since we are streaming our movies etc.
• is there a better way of obtaining and setting up your own domain also in terms of privacy and reliability than with a bigger company offering such services?

Thanks a lot for your feedback!

Edit: An important fact I forgot to add in my main post is that during these issues, the general server connection should be fine since it is located at a friends house and his internet connection is unaffected (e.g. we could still talk in Discord normally and he had no internet issues whatsoever)
