The broadcast itself ran into “technical troubles” and went online later than scheduled.

The problems have been caused by aged energy infrastructure and a dwindling external supply of fuel.A fire in 2022 at the Matanzas oil storage facility also greatly contributed to the island’s energy crisis. The five-day-long blaze was triggered by an explosion sparked by a lightning strike and resulting in the destruction of some 40% of the country’s main oil storage facility. Source
