### Issue

Hi

I have the latest version of the plugin, as well as homebridge, etc. everything used to work, but for some reason it stopped. The photo shows two ping commands - the upper one when the computer is unlocked, the lower one when the computer is locked. Why doesn't ping print 0, what to check?

When I follow these steps:
1. Make sure `logLevel` is set to `Debug` on all `NetworkDevice` accessories
2. Run `homebridge`
3. Let it run for a couple of minutes
4. Try to turn a device on or off using the plugin
5. Wait one minute
6. Repeat step 4

I get the following log:
