Description

Youtube-dl has been working fine for quite a long time, but about a week or so ago began failing to log in, with the message "Warning: Unable to login: Invalid password". None of the open or closed issues helped address this, and I jumped through a bunch of hoops trying to resolve that error. But after clearing my browser cookies, removing all accounts from google but the one I'm trying to use, and saving those cookies to a file, I'm getting a different error... nor sure if that's progress or not :|

The documentation says that a 400 BAD REQUEST usually means a corrupt cookie file. But deleting the cookie file and allowing ytdl to recreate it gives me the same response - 400 BAD REQUEST. I've I've gone over the cookie file I'm trying to use, and everything looks fine, anyway. I've made sure the user agent string for ytdl matches the user agent string for my browser, and I've tried using the default user agent string in ytdl.

Logging in through my browser works perfectly fine. YTDL works perfectly fine to d/l individual videos that don't need me to supply a username/pw. But trying to d/l any video or playlist using my username and pw gives me a 400 BAD REQUEST on the login.

What else can I try/where do I go next? I'd love to see the request that's being sent, but I don't see anywhere ytdl supports dumping that.
