Today my Smart bulb stopped working with Alexa voice control (has been working fine for about 2 weeks prior). When light switched on, it flashed twice. I reconnected it via the App to my network and the app can now switch bulb off and on but Alexa cannot.
I have reset the bulb, disabled then reenabled the skill on Alexa and set it all up from scratch again. Again works ok with the Tapo app, Alex identifies the device but cannot control it - states "Server is unresponsive."
