Impossible to view workout details

A Workout I did this morning is visible in my activity feed, but the detailed view activity page
( https://www.zwift.com/activity/564169425922141280 ) never loads.
I see a request of a json file to AWS returning an error : Unsupported Authorization Type

Also this workout did not sync to Strava or Garmin.

If the following instructions don’t work for you and strava says there’s an error with the fit file then try messing around with fixing the fit file using https://www.fitfiletools.com/
