(Tailscale engineer here)

What's the bug? I hadn't heard about this.

Metrics show no drop in iOS control plane connections.

Here’s the post i put up on the forum.

Other posts had some troubleshooting guidance that wasnt effective. Note that it only failed on iOS. Still using it on my Debian boxes.

If you could point me at anything I would be very grateful. I’m using some other VPN container now that i don’t like!

I had a similar issue, clearing history and website data in Settings > Safari and reinstalling fixed it for me. I may have rebooted the iPhone as well for good measure.

I've been using tailscale for a couple years. wrt ios every couple of weeks all traffic on my phone stops and I need to open the tailscale app and toggle the active switch for traffic to start flowing again. I don't have that problem with my other devices.

I've actually had that happen on Android, seemed to somehow kill even all non-tailscale traffic too

The way it works on phones is these apps operate as full VPN due to how network permissions for apps are handled. When you turn on tailscale, tailscale will pass through traffic it doesn’t need to touch. that’s also why you can’t have two vpn apps running at the same time.
