2. There are router and/or firewall problems.
• Reset the firewall settings on the modem or router. The remote monitoring
system requires open communication to 168.61.54.255 on port 8884 and
40.114.00.153 on port 8885. Refer to the modem or router owner’s manual
for the proper procedure.
• It is also possible the Internet service provider is blocking communication to
these addresses or these ports outside of the customers network. Contact
the Internet service provider for additional troubleshooting if the generator
set is still not able to connect after the customers internet and firewall
settings have been verified.
3. The Connect Cloud is unavailable.
• Verify availability by accessing the Connect Cloud from another device,
and/or another browser.
4. The control board software is not current.
• Ensure the control board software matches the latest version available.
See the Control Software Updates section for information on how to
perform control software updates.
5. There is a generator set control board problem.
• If there is still a problem after you have completed all other troubleshooting,
it is possible the control board has a problem and must be replaced.
However, it is very unlikely that the remote monitoring portion of the control
board has a problem if all other generator set functions are operational.
Mobile Device or Computer Connection Problem
Possible Causes:
1. The Connect Cloud web page does not load because of an Internet connection
problem.
2. The mobile device or computer has an Internet connection problem.
3. The customer’s modem or router does not have Internet connectivity.
Diagnosis and Repair:
1. The Connect Cloud Web page does not load because of an Internet connection
problem.
a. Open your preferred browser and navigate to another web page to verify
the Internet connection.
b. Reset the Internet settings or access the Connect Cloud from another
browser.
2. The mobile device or computer has an Internet connection problem.
a. Make sure that at least one of the following conditions is true:
• The mobile device or computer is connected via an Ethernet cable.
• The mobile device or computer Wi-Fi is enabled and connected.
