Intermittant connection from Raspberry Pi 4

Raspberry Pi

Hi all :wave:

I’m having some issues connecting to a Raspberry Pi via/over Tailscale. The interesting part is that the connectivity is almost comically cyclical:

mtr looks like this:

Basically, on … off … on … off. The set up of the Raspberry Pi is behind a Comcast XFi (?) router/modem combo. I’ve observed the same things happening whether my client device is using my home network or tethered via mobile.

Curious in this scenario what are the things I should be looking at first to try and diagnose the issue? I’m thinking there is some sort of issue with STUN?

Happy as well to share logs from my tailscale.service

You’re running 0.94-236, from Jan 14th. That is the oldest build that any Tailscale user is running. :trophy:

There have been thousands of fixes and improvements since then. :slight_smile:

So the first thing I’d do is update to the latest stable version.

But props on being an early adopter! You were using Tailscale before I joined the company a ~week later. :joy:

Haha cheers :+1: and congrats on joining!

So the first thing I’d do is update to the latest stable version.

I did check this and forgot to mention:

 $ tailscale --version
1.2.8
  tailscale commit: cde3a23b6649ed448a9a94bd776043fb09e966d5
  other commit: 1f7ecb611d82fb6f95f6a65fd61fc2265f98dc37
  go version: go1.15.4-tsf9db43b

I thought I may have mistakenly had two services running (one from the OG way to install on Raspberry Pi and a second from the fancy new apt package) but unsure if I need both these things? It appears I have both a tailscale.service and tailscaled.service I assume the tailscaled creates the .sock file that the tailscale.service listens on.

Also was just looking at the Perkeep project the other day which I think I saw your name attached to? Had never seen ~‘self-hosted uniquely addressable block storage’ work so seamlessly before other than IPFS.

Yup that was my problem. Doing a bit of history digging I found I had curl'd relaynode.arm back in March and then installed Tailscale via apt later on which was causing the conflict.

Here’s the steps I took to get back in good shape.

  • Disabled both tailscale.service and tailscaled.service
  • sudo apt remove tailscale --purge
  • sudo rm /usr/sbin/relayode.arm
  • sudo apt install tailscale
  • Then re-enabled tailscaled.service
  • Ran tailscale up -force-reauth (tailscale up would just hang forever)

And I was then good to go :+1: – now seeing no disconnects now as expected.
