Well the logging clearly explains what's going on.
The plugin determined that there isn't a connection to the internet. It does this by first pinging 8.8.8.8 and if that fails then pings 1.1.1.1
The question then remains why both of these checks are failing if, as it seems, the server actually is connected to the internet.
Edit: seems like I pushed the wrong commit so it just pinged 1.1.1.1 twice. Try the new version (2018.09.10c) I just pushed
