If Hulu charged your card but still says "Unable to start your trial," make sure you can get a free trial.
Hulu only gives free trials to new subscribers or qualified returning subscribers for certain plans.
Next, check your Account → Billing page to see if the charge is just a temporary permission hold and not a real subscription fee. These can show up even during a trial.
If the charge is real and you can't get to the content, check to see if you have more than one Hulu account or if you subscribed through a third party, like a cell carrier or a streaming bundle. This could make the trial harder.
If the issue persists, share your experience and consider filing a complaint on Xolvie to seek a resolution.
