Description

It seems that there is an issue with extracting from websites if all 4 characters in the URL are numbers. The example is one I've found that should be accessible to all with an account, that demonstrates the issue specifically.

To get an account from player.stv.tv, you will need proof of being in Scotland - a postcode from https://www.townscountiespostcodes.co.uk/postcodes-in-scotland/ should do it

I've also found this issue with youtube-dl and episodes with integers in.
