Chamberlain MyQ Series - Green LED on the Internet Gateway Is Blinking

CONNECTION ISSUES (CONTINUED)
Problem:
Green LED on the Internet Gateway is blinking
If the green LED on the Internet Gateway is blinking, the Internet Gateway has obtained an IP address from the router, but
the Internet Gateway is not connecting to the MyQ Server.
Solution:
Determine if a router setting (e.g. firewall setting) is preventing the Internet Gateway from communicating with the
Internet.

• TheInternetGatewayrequiresUDPport80tohaveaUDPtimeoutof180secorgreater.
Determine if a network security appliance (firewall, e.g. SonicWALL

closes the Internet Gateway connection to the server after the Internet Gateway enters its sleep state and reduces
communication to the server to once every 60 seconds. When this occurs, the Internet Gateway will take up to 2 minutes to
recognize the connection to the server is lost before trying to re-establish connection. The process will continue to repeat.
