✅ Have you read and understood the above guidelines?

yes

📜 What is the name of the script you are using?

Jellyfin.sh

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/jellyfin.sh)"

⚙️ What settings are you using?

  • Default Settings
  • Advanced Settings

🖥️ Which Linux distribution are you using?

Ubuntu 24.04

📈 Which Proxmox version are you on?

Linux proxmox 6.14.11-4-pve #1 SMP PREEMPT_DYNAMIC PMX 6.14.11-4 (2025-10-10T08:04Z) x86_64

📝 Provide a clear and concise description of the issue.

Have tried default settings, advanced settings using default options. It always hangs on LXC network. then it prompts me to do fallback dns and eventually says I failed the script. My router is appearing to give "jellyfin" an IP address but I don't seem to be able to connect to it. Meanwhile I've installed other LXC scripts from this site that work great.

🔄 Steps to reproduce the issue.

run script in terminal. select default, or advanced and just run through the default settings. same result

❌ Paste the full error output (if available).

I'm encountering the same problem. Does "Tailscale issue" mean this is a known issue that has been addressed or at least discussed somewhere else? Could you provide a link for reference?

Thanks for the hint. There's a good discussion about it in #7674, with a link to the relevant Tailscale docs which says:

Two options to mitigate this behavior are:

  1. Configure tailscale without MagicDNS on the Proxmox host with tailscale set --accept-dns=false.
  2. Create a file named /etc/.pve-ignore.resolv.conf within each LXC's filesystem that will tell Proxmox not to overwrite /etc/resolv.conf.

Unfortunately, the first one isn't an option for me. I tried the second option (related Proxmox docs) but it didn't seem to fix the issue. Thankfully, #111 mentions a third option, which is to use the advanced settings to manually set the DNS. From the command line, it looks like this:

This worked for me! Obviously, if you're running your own DNS server, use that IP instead of 1.1.1.1.

These two issues have the same problem. Creating backlinks for anyone else trying to find a fix.
