To be investigated

I've launched https://farm.openzim.org/pipeline/a3daa3da-c5db-4548-89f7-37ad76969b01 to confirm it is not a general issue (CI doesn't check Youtube videos anymore because Github worker fails to fetch them).

Sadly, issue is not linked to apod.nasa.gov ; youtube video is now also broken in test website, making it a clear general issue
