I am unable to run Zwift with my Computrainer. My Computrainer runs fine on Comm Port 3 with the Racermate software suite as well as Trainerroad. I always connect my C trainer, then run the coaching software to ensure communication is good between my trainer and my computer.
I then shut off the Racermate software (unless I am using it) and run the alternate sofware with no issues (Trainerroad generally).
When running Zwift, the software searches for and finds my Ctrainer, then pairs with the trainer. Immediately thereafter, it gives a “Connection Lost” error, and I am unable to reconnect.
