Troubleshoot Sunrise Communications issues

It appears that Sunrise Communications is blocking the Tailscale service.

Specifically, Tailscale has been (incorrectly) flagged by Sunrise's Surf Protect as a potentially malicious application.

To use Tailscale, you'll need to work with Sunrise support:

• Find your Sunrise site ID.
• Contact Sunrise support at Sunrise support, and ask that *.tailscale.com and *.tailscale.io be added to the exclusion list for your Surf Protect subscription. Alternately if desired, you could remove Surf Protect from your account.
