Troubleshooting
The broker connection cannot be established .
The status shows “DISABLED” (the Green LED is off): there is no configured
connection or the cLAN is waiting for the next try.
The status shows
“Connecting…” (The Green LED blinks rapidly).
If the LED blinks rapidly during several seconds (a minute or more) verify:
That the equipment to which you are trying to connect is not behind a firewall
which is filtering the connection.
You might not have configured the broker's public IP address and/or forgot to
open the TCP port in you router.
If the LED blinks rapidly a few seconds (2 or 3) and then blinks slowly verify:
That the IP address and port to which the cLAN is attempting to connect are the
correct ones.
That there is no reason why the server is rejecting the connection request (ex.
That is requesting identification or authentication).
A connection is established and then it closes
Verify that there is no reason why the server is rejecting the connection request
(ex. That is requesting identification or authentication).
The connection is established but the communication fails
If the Green LED remains constantly on and it does not blink, is indicating that there
is no data reception or transmission. If the Green LED blinks sporadically, it is
indicating that data are being sent and/or received. In any case verify:
That the broker connection was made to the correct IP address and port
