I have been using HomeKit on an iPhone 8 and 6s to control six Philips Hue bulbs through my 4th-gen Apple TV for the last few months with no issues.
Yesterday my Amazon Echo randomly stopped being able to control them so I reset the wifi settings(on the echo) and that solved the issue. At the same time my HomeKit also stopped working. All lights now give "no response" warnings.
I can still use the Philips Hue app on my iPhone to control the lights as well as through Alexa.
I am wondering why this may have happened and how to solve the issue.
