Ride not saved

I performed my first ride on Zwift today,on exiting program a message came up saying it could not sign me out, and the program closed.
When I logged back in, my ride is not recorded in my acitivities, although there is a FIT file in my laptop drive that I have managed to upload to my Strava (https://www.strava.com/activities/259678508) .
Is there a way I can link this FIT file to my Zwift account page so my ride is recorded ?
