My Phone Stopped Working

A yellow light or loss of dial-tone can occur due to the following causes:

  • Degraded or lost internet connectivity
  • Restrictive firewall rules
  • HH Maintenance Window (servers under maintenance)
  • Incorrect credentials
  • High latency (>= 400ms)
  • IP blocking (which can be caused if you disturb your login credentials in the phone)

Some possible solutions to try before opening a ticket:

  • Reboot your cable modem then your router
  • Check connecting network cables
  • Review firewall rules. Ensure your phone can get OUT.
  • If all fails, try placing your Phone in the DMZ of your network, and test (DO NOT leave it in the DMZ, this is just for troubleshooting!)
  • If HH is doing maintenance, we will do our best to announce it ahead of time, but check the Discord group for announcements.
  • Reboot your phone
  • Re-provision your phone

If re-booting your router doesn't fix the issue, then you can print out the Troubleshooting Worksheet below to help you.
