Connection lost when moving between office and home

When I move between the office and work, I have noticed that Catlight seems to show as Offline. Pressing refresh or Ctrl-refresh doesn't solve it. I need to quit the app and restart it to get it to connect again.

I've attached a screenshot... a popup box did appear at the top of the window saying "Error 500, check the catlight logs for more info", but that doesn't seem to have shown up in the screengrab.

Logs attached.
