I was experiencing the authentication flakiness mentioned in #158 and this has been working consistently for me for 3 days now (thanks for the docker image to test easily with!)

Glad to hear that @manicExpressive . I've rebased these changes onto the latest release so I'd recommend pulling the newest docker image when you get a chance. Let me know if it's still working for you after a few more days and I'll get everything merged.

Auth failed after 2 days which I only just noticed 3 days later because of weekend / conference stuff.

Just reset everything and grabbed a fresh cookie (which I had to "hard refresh" the Chrome instance of music.youtube.com was operating in some kind of cached mode).

This seems like kinda normal "using this cookie for auth is a little sketchy" stuff rather than a bug, happy to report back in a few days again to see if this seems consistent.
