Please review the checklist and take the indicated action (or explain why it isn't applicable) in each case.
In particular, you seem to have stripped any information showing the command-line options. Please paste the complete verbose log of your yt-dl command.
You likely have some networking issue related to your proxy configuration or some external service.
If the resource does require a login and you still get the 400 response, you may find that using a cookies file exported from your logged-in browser session with --cookies ... instead of -u/--username ... and -p/--password ... works.
