Lights not responding

[d19r59m]

Hi, I'm new to this forum. I installed the Segled LED's along with a segled hub at the same time I installed a Echo Plus, Echo and an Echo dot last November. Connected all lights to my Echo's and everything worked great for 6 months. Now all of the sudden Alexa says the lights are not responding for the last two days, no matter which scene I ask her to turn on she that scene is not responding. What can I do to correct this? I have no idea. Thank you for any help.

Solved: Went to Alexa app and deleted all lights & groups, also disabled the Sengled skill. Enabled the Sengled skill and discovered all lights again and recreated all light groups. Problem solved.
