Tailscale version 1.35.24 (also tried 1.32.3 with the same results)
Your operating system & version Unifi OS UDR 3.0.13 / Debian 11 (bullseye)
I’ve been trying to set up tailscale on my Unifi Dream Router using this tutorial.:
I was able to install tailscale 1.32.3 on a Unifi Security Gateway with the help of the comments in that link, run tailscale up and authenticate successfully. That install seems to be running just fine.
I was able to get the daemon running on the UDR, but then “tailscale up” hangs infinitely and I can’t get past authentication.
Even before running “tailscale up” the tailscale daemon logs indicate that the daemon can’t connect to the log server. I compared the logs from the working USG to the UDR, and it seems like there might be a problem with DNS configuration on the UDR, or maybe a firewall issue? Here is a snippet of the tailscaled log without running tailscale up, past this the log is just a bunch of connection errors but I can’t have more links in this post.
