I also had this problem. When mininet started up i observed the following output

Connecting to remote controller at my_ip_address:6653

Which was curious because i had not started the onos controller.

So i found out what was using port 6653 using: sudo lsof -i:6653 then killed that process.

Starting the onos controller and mininet, then on onos cli > devices returned correctly
