Elite Drivo not adjusting resistance frequently

[Steve Rode]

My Elite Drivo doesn't adjust the resitance anymore following workouts on my Garmin head units - both 1030 and 1040 solar. The speed shows up consistently but the power drops and comes back frequently, and the smart trainer hook up shows it's connected, but doesn't do anything most of the time. Some times it will adjust briefly then it stops. I get notifications once in a while that the trainer is connect which I assume means it's dropped. The blue light isn't on and the green light goes from solid to blinking. I've used the trainer in the same location for years and nothing has changed so it's not external interference. Is there a fix possible?
