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.
