Nothing through headphones

I have the UR22 and Cubase AI
Fostex monitors connected via TRS leads to Out 1 & 2.
Nothing comes through headphones. Any help would be appreciated.
And another thing, in the VST Device set-up > Control Panel, the Direct Monitoring checkbos is greyed-out, so can’t use that function. Is this connected to the headphone problem???

Any one with a quick tip?
It’s a very simple question.
