### What issue do you have? Please be as thorough and explicit as possible.

My Govee plugin has stopped controlling my LED light strip. It was working fine but now will not control them. The log file is just showing _25/10/2021, 14:22:49 HOOBS Govee WARNING [TV Backlights] has been reported [offline]._
Control is working fine on my local wifi network using the Govee IOS app. I have reapplied the API Key with no change.
If I change the power status or brightness via the IOS Home app, I do see it in the hoops logs. I've enabled debugging and see the following line: _[TV Backlights] has been reported [offline] via API, so update may or may not be successful._
