Hello @bruno.debrida and welcome to the Cayenne Community. I’d be happy to help.
Since it looks from the log like the install really did go OK, I suspect this could be because port 8181 might be closed on your network, and this port is required for our Pi agent software to connect to our cloud server. If it can’t make this connection, then it may not be able to tell the server the install was OK and start transmitting data to Cayenne.
You can use telnet to check if the port is open. This is not installed by default any more so you can install it using sudo apt-get install telnet
If the port is open you will see the following (your IP addresses may or may not be the same as mine):
pi@raspberrypi:~ $ telnet cloud.mydevices.com 8181
Trying 54.165.135.17...
Connected to cloud.mydevices.com.
Escape character is '^]'.
Connection closed by foreign host.
If the port is closed you will see the following (your IP addresses may or may not be the same as mine):
pi@raspberrypi:~ $ telnet cloud.mydevices.com 8181
Trying 52.6.151.66...
Trying 54.165.135.17...
telnet: Unable to connect to remote host: Connection timed out
