Tacx Flux watt dropouts

I am using a Tacx Flux with a Macbook. So far no problems. Everything was fine. In today´s ride I had a couple of dropouts concerning the watts shown on Zwift while riding. Each only for about 5-10 seconds. Then the watts were shown again. Any ideas?

 

Are you using BLE or ANT+?
