On my iOS device, which doesn’t give me an IPv4 address when I’m connected to just cellular, I am unable to access any devices on the tailscale network or through relay nodes. If I connect to a wifi network on IPv4, everything works fine. Based on the link below, it would seem like this should be working. Any help would be greatly appreciated.
I’m having exactly the same issue since my cell provider now only issues IPv6 addresses to mobile devices. I can no longer access any Tailscale device from the iOS app when on the cell network.
Works fine on wifi when I have a IPv4 address.
Works for me over a pure IPv6 mobile carrier. I suspect that they are inhibiting UDP???
