Green Led On The Internet Gateway Is Blinking - Chamberlain MyQ Series Troubleshooting Manual

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.
• Review the router's settings and manual.
• T he 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
• D etermine if the network security settings are preventing connection of the Internet Gateway to the Internet.
• T he Internet Gateway requires UDP port 80 to have a UDP timeout of 180 sec or greater. SonicWALL®'s UDP
timeout must be adjusted to be 180 sec or longer for both inbound and outbound data traffic.
SonicWALL Fire Wall

MyQ workaround for a SonicWALL Network Appliance.
Problem:
The problems listed above are caused by SonicWALL's factory default UDP connection timer being set to 30 seconds which
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.
When a MyQ device is behind a SonicWALL Network Appliance, the following MyQ app performance issues may occur:
1. Difficulty controlling a MyQ device through the MyQ app.
2. M anual operation of a MyQ device may not change state on the MyQ app (commercial door is closed by pressing
wall control, but app shows door open).
3. Upon power cycling of an Internet Gateway the app will work for a brief period of time and then enter a non-working
state.
Solution:
The SonicWALL UDP connection timer should be changed to 120 seconds or greater. LiftMaster recommends a minimum
value of 180 seconds. The timer must be changed in multiple locations.
1. The default UDP timer should be changed, which will change the UDP connection timer for any new rule
made to the SonicWALL.
2. A ny current LAN -> WAN rules must have the UDP connection timeout updated manually. Set "Defualt UDP
Connection Timeout (seconds):" to "360" and set "UDP Connection Inactivity Timeout (seconds):" to
"360".
