Thanks a lot for your suggestions and feedback! I also would like to use services within the EU, so I will give Bunny a closer look.

I am in the same boat (learning on the go, living in EU and using fail2ban and reverse proxy although I use nginx). Sounds good that it runs so well for you! Where did you register your domain? I’ll look into BunnyCDN as well.

I looked into porkbun and it seems that they already offer a Cloudflare API for dynamic DNS. Why did you choose to separately use Cloudflare? Bit otherwise it looks promising to give it a try.

I have a cronjob that runs every minute to update the IP address. I could try to increase it to every hour or so. In the beginning I tracked how often the ISP changed the address and it was roughly like once every 24-30 hours, cannot really remember.

For me it seems like a very similar issue with these inconsistencies. Why would your think it does not really match? Especially given that the network connection of our server location is always fine during these down times?

For me it seems like to be a similar issue with the duckdns inconsistencies.

So there could be a potenital issue where the correct IP address has been sent but the record has not been updated … Yesterday for example we faced the issue that at least one of three could not access the server. Suddenly it worked for someone who could not connect, only for him to lose access again after a couple of minutes. We all have been in Discord during that time, and the internet connection was fine for everyone.

The server is running at my friends house who has a fiber connection. When we face these connection issues, it does not necessarily mean that all of us cannot access Jellyfin but often times only a couple of us cannot access (same error as if you mistype a web-address, so it cannot resolve the domain name). During these periods of connection issues, the internet connection of my friend is working completely fine. I have a script running that constantly sends the current IP address to the dynDNS provider. I also looked into how often our ISP changes the IP address and it is not very often and not during these issues.

Thanks, yes I also use a script that constantly sends the current IP address to the dynDNS provider. I could be completely wrong, but the internet connection of my friends house where the server stands is fine even during these connection issues. So I would blame the DNS resolution, but it is also my first time running a server.

I have a script running which sends the current IP to our dynDNS provider. I would assume that this is fine then?

I am using dynv6.com. The reason I blame the DNS resolution is because when I have issues connecting (as if the domain is not available), it does not mean that my friends cannot connect either. The server is at a friends house who has a fiber connection and who has no issues when we habe trouble connecting again. I could be totally wrong, but to me it sounds like dynv6 has some troubles.

I also have a script running, which constantly updates dynv6 with our current IP address.
