Hi, I have four machines that or on my Tailscale network and which are currently online:
- two Synology NASes running Tailscale 1.16.2 [named “orb” and “gem”]
- one Linux machine running Tailscale 1.22.2 [named “wok”]
- one macOS 12.3.1 machine running Tailscale 1.20.1 [named “ink”]
The NASes and macOS machine are on the same subnet. The Linux machine is on a different network, over the Internet.
The macOS machine can’t connect to any other machine on the Tailscale network, nor can the others connect to it. The others can connect to each other fine.
tailscale status on the macOS machine says:
# Health check: # - haven't heard from home DERP region 5 in 13m40s 100.68.121.31 ink heycam@ macOS - 100.113.228.4 gem heycam@ linux - 100.69.101.96 orb heycam@ linux - 100.85.134.13 wok heycam@ linux -
Earlier today (before a
tailscale down /
tailscale up) it was saying this:
# Health check: # - ReceiveDERP is not running # - ReceiveIPv4 is not running # - ReceiveIPv6 is not running 100.68.121.31 ink heycam@ macOS - 100.113.228.4 gem heycam@ linux - 100.69.101.96 orb heycam@ linux - 100.85.134.13 wok heycam@ linux -
tailscale netcheck on the macOS machine:
cam@ink:~ $ /Applications/Tailscale.app/Contents/MacOS/Tailscale netcheck Report: * UDP: true * IPv4: yes, XXX * IPv6: no * MappingVariesByDestIP: false * HairPinning: false * PortMapping: * Nearest DERP: Sydney * DERP latency: - syd: 20.9ms (Sydney) - sin: 90ms (Singapore) - blr: 123.2ms (Bangalore) - tok: 148.5ms (Tokyo) - sfo: 167.1ms (San Francisco) - sea: 183.6ms (Seattle) - dfw: 194.3ms (Dallas) - ord: 211.4ms (Chicago) - nyc: 215.2ms (New York City) - fra: 243.1ms (Frankfurt) - lhr: 246.5ms (London) - sao: 349ms (São Paulo)
What might be causing this lack of connectivity?
