2. Check that the connection to the internal connector on the communication board is
properly done.
3. Check that the selected communication option is properly configured.
4. Use a method independent of the SolarEdge device to check whether the network

router and connect to the Internet.
5. Check whether a firewall or another type of network filter is blocking
communication.
