I'm using netplan for my DNS and I have it set as 1.1.1.1 and 1.0.0.1. I changed the 1.0.0.1 to 9.9.9.9 like you recommended and I still got nothing. I could ping jellyfin.org though:

Code:

--- jellyfin.org ping statistics
3 packets transmitted, 3 received, 0% packet loss, time 2004ms
rtt min/avg/max/mdev = 12.455/12.707/13.162/0.321 ms

I am still however getting the network unreachable when updating posters.

Then how are you connecting your media, is this a Samba or NFS share by chance? Because that can also pose it's own permissions set on files from a NAS or the likes onto the files and prevent Jellyfin from having the ability to write to it. Depending on how a network share is mounted, it can let you change the permissions of files, but not let you create new files in that said mount point. I've seen this happen to people a few times for multiple reasons not related to Jellyfin.

I have no idea what samba or nfs are but im pretty sure its not. I'm working on getting an *arr stack set up but I'm having a bunch more poblems with docker. Currently my setup is: Download torrents to home desktop -> sftp into laptop server and transfer them wirelessly.

Also do you have any backups of before you had this problem or before you were on Ubuntu 26? Like on Ubuntu Noble? Maybe one of your databases went bad. I had this happen in Jellyfin upgrading from 10.11.X versions. 10.11.3/4 had broken the "Items" and other pages access so my WatchState couldn't connect. Then in 10.11.8 to 10.11.9 it completely wiped my databases. I had to restore my VM so many times with 10.11.X builds just to upgrade them from a lower point to a higher point to not have database breaks and other issues.

No I only just made this server the other day on Ubuntu 26, I haven't used any earlier versions of ubuntu for this project.

So it pings outside the network. Which is good, so you are getting internet access.

Samba and NFS is just file sharing methods over your network. I remembered you mentioned about having multiple things for stuff. So I didn't know if your media was stored on a NAS or NAS like setup that was shared over the network to Jellyfin. I asked to be sure there was no other means of potential permission issues as these could create an extra layer of permissions.

Yet if I am not mistaken you are also getting errors trying to pull a docker image from a URL correct? This rare thing happened to me once with Docker and my DNS once on one of my VM's. So it might be happening to you. Docker does this thing to isolate networks and creates a vlan of sorts and it can even overwrite the systems DNS. When this first happened I too was using "Netplan" on a Ubuntu 16 VM (I believe 16 it could have been higher. So many version numbers, lol) I was stumped to why my DNS kept getting overwritten and I couldn't understand because I set it all correctly. Turns out when I turned off everything of Docker fully it would connect and use the proper DNS servers I wanted, but if I brought Docker back up it instantly overwrote what I had. What I ended up having to do is change from using Netplan and get rid of that all together. I don't know why exactly it did it and I didn't go too deep into it since my solution of not using Netplan worked, but yeah...

Anyway, if you "sudo systemctl disable docker docker.service docker.socket containerd" & "sudo systemctl stop docker docker.service docker.socket containerd". Then test if you can connect to OMDB or TMDB through Jellyfin. If not try restarting the computer real quick and try once again. If it does work then it was likely Dockers network stack messing with your DNS. Which means you might want to try using another network method and get rid of Netplan. However, if it doesn't work, you can do "sudo systemctl enable docker docker.service docker.socket containerd" and "sudo systemctl start docker docker.service docker.socket containerd" to get Docker stuff all up and running again.

All that being said, if even Docker images are not being pulled and links for those are being blocked out. Well something is messing with your network and stopping it from happening. Usually a DNS issue is the problem in most cases. However, you could try VPN connections to bypass somethings. If a VPN works and gets things connected you might have a firewall in your router/modem that accepts UPNP like connections but is blocking things for some reason. Yet I would imagine the issue is on the Ubuntu install and not that, but some ISP's and/or equipment can have pretty strict blocking rules.

It is still not working. I'm seriously considering doing a fresh install and resetting, as this has been an issue since I started. I'll at least give it a go on a VM first to make sure, but if there's no other solution that you can think of then I'll probs just call it quits. I tried setting up openvpn initially but I had too much trouble trying to get that set up, but I'll try with another. If you know of any simpler ones that would be super helpful. Sincerely, thank you so much for your help and support, I really appreciate you taking the time out of your day :) I'll give it one last go and let you know how it does, but other than that I'm probably done.

Well this for sure has to be a network issue. If the network issue doesn't happen in the VM then something was set to that IP maybe, in like a firewall or something. Because it's clear at this point, that you have a network issue if even your Docker pulling images have the same errors as OMDB and TMDB. So it's not Jellyfin in this case.

The only possible other thing inside that Ubuntu install you have now I could imagine it being is perhaps your Netplan configuration. When you apply it via the command, are they any errors, warnings, or anything? Have you tried nuking Netplan and using another means of managing your network in Ubuntu 26? Because that is the only other thing I could say do if it's not your Netplan configuration.

I tried setting up openvpn initially but I had too much trouble trying to get that set up

Did you do this on this same machine and not wipe the configurations? Because if you did, and the VPN configuration is still in place and running, even if not connected. Well that could very well be what is screwing up your resolving of URLs. VPN's can force you to use the DNS set from that VPN connection to tunnel everything through the VPN. By trying to set that up, you could very well have created this problem not knowing it. There are a few ways a VPN can be setup and how it tunnels the traffic. So misconfigurations could have lead to this.

If you know of any simpler ones that would be super helpful.

The most simple one to setup and sort of newest is Wireguard. There are even Docker configurations for Wireguard that generate the keys and everything for you and web interfaces. I think one of them is literally called "Wireguard Easy". I setup mine via system packages so not sure if that is correct on the name. 

However, if you wish to use Wireguard and don't mind someone else hosting it and having a sort of portal you login. Tailscale is technically free and I believe it allows like four devices for free on a free account. I could be mistaken on the exact amount. Again I don't use Tailscale and setup my own Wireguard setups so only going off vague details of what I sort of heard and read in the past.

It is still not working. I'm seriously considering doing a fresh install and resetting, as this has been an issue since I started

If you're starting fresh, maybe go down a version of Ubuntu to like Noble then. Since Ubuntu 26 in this case is now using Rust coreutils and has majorly rewrote all existing C code into Rust and it's not been long term used by everyone in a LTS as of yet. Maybe it's not agreeing with your system some how? Which messing with the network stack.

That's just a random thought. Crazier things have happened, but I still want to think it's a problem like I've described before, being a your configuration of OpenVPN, the Netplan config, firewall, and/or configuration of sorts in a router/modem. Because a router/modem can even block the usage of alternative DNS usage if setup that way. (It's been a while since I used a pre-made router since I VM my router/switches. Using IPfire, OpenSwitch, and OPNsense. Though I would imagine most modern software would allow that now or your ISP might be a pain and set that by default. So that they can set what you can and can no resolve with their DNS servers.)

Anyway, pretty much anything that messes with your network and could be blocking the use of third-party DNS. That is what you need to eliminate. Because that has to be the issue here. As you can't resolve a lot of URLs it seems.
