Troubleshoot Tailscale domains and sites unreachable
Last validated:
If your network and internet connectivity are working as expected, but you cannot reach any of the Tailscale sites, including our corporate site, documentation, and admin console, this may be because we were erroneously added to an internet blocklist. To prevent temporary DNS blocking to our sites, we recommend adding the following entries to your DNS service allowlists.
*.tailscale.com
*.tailscale.io
We support a wide variety of DNS services, including Control D, Linux DNS, NextDNS, and Unbound DNS in OPNsense.
