For YouTube videos, please provide the exact video you are transcribing. There are lots of variations of videos that can result in failed translations due to how locked down YT scraping is at any given time.

Just tried to replicate with this video - https://www.youtube.com/watch?v=n9Tn6-zFwCQ
No issues, so may be video specific

Then this is certainly client side. I am running this from a home IP. Are you on an cloud instance? YT endpoint may be blocking any cloud IP ranges (common)

Yes, this is running on a container in Azure. I will try to see if I can replicate it on a local container
