[Youtube] Download error is silent during subtitle download

Description

Reproduction:

Use (old) legit cookies across 2 IPs (residential IPv4 and IPv6)
Videos, comments download fine, no “too many requests” errors
yt-dlp tries to download subtitles after fetching comments
No error, exit code 1

Reason:

I ran into “too many requests”, but yt-dlp showed no error at all. Instead it exits silently and gives no error message

Expected:

yt-dlp should print a correct error message

Workaround:

Change cookies (e.g. empty cookie file works again). Looks like there’s harsher rate-limiting per cookie identity instance since browser/empty cookies work fine on the same IP.

curl with properly loaded “broken” cookie file returns the automated requests error:

curl -c broken-vtt-cookies.txt -b broken-vtt-cookies.txt 'https://www.youtube.com/api/timedtext?v=GgpTBPTd_DA&asr_langs=de%2Cen%2Ces%2Cfr%2Cid%2Cit%2Cja%2Cko%2Cnl%2Cpt%2Cru%2Ctr%2Cvi&caps=asr&xoaf=4&hl=en&ip=0.0.0.0&ipbits=0&expire=1648012028&sparams=ip%2Cipbits%2Cexpire%2Cv%2Casr_langs%2Ccaps%2Cxoaf&signature=<removed>.<removed>&key=yt8&kind=asr&lang=ru&tlang=en&fmt=vtt' --verbose
