On demand erorr

Just like this person https://forum.telus.com/t5/TV/Persistent-error-message-on-several-on-demand-show/td-p/168551, I am having trouble with playing an on-demand show. I had a show scheduled to record on time shift, but the guide was incorrect and recorded the wrong show. So, a few days this week I've tried to watch the episode on-demand, and it comes up with an error message. "Unable to play video. Please try again later." With options of "OK" and "Retry"

The episode is season 8 episode 15 of 911 on Global on-demand.
