Zwift not connecting to tacx flux2

I’m having issues getting Zwift to connect to my trainer- I’ve been using my zwift/tacx combo several times a week and just went to train with it this morning, but zwift isn’t recognising I have a trainer to connect.
I’ve reset both the trainer, my iPad, the Zwift app and still no luck. Although my forerunner 745 will connect, it seems.

Trainer will happily connect to the tacx app, so it feel like this is an issue on the Zwift side of things.

Anyone else having this issue? Or know of any possible fixes?
