Existing Signin causes other Instances to typically Fail Signon process

[effleurager]

When using youtube-dl concurrent to another signed in instance, signin is inconsistent - outright failure occurs, preventing access to private playlists, possibly gated videos as well, however this is not always the case. Between 2 clients, I've been unable to see any pattern; somehow both can fail to signin.

Are the credentials specified in .netrc valid for https://www.youtube.com/playlist?list=PLARhCYccw3tb0ewDzW4eE28DNc9V_oIZE? If not, you need to specify additional --username and --password in the command line.

They are definitely correct, as signin is successful on occasion, say I were to leave it in a loop which restarted on a non-zero exit code - I regularly have to update it due to Google's insistence on ostensible suspicious behavior.

I regularly have to update it due to Google's insistence on ostensible suspicious behavior.

I have the same problem. Since a few weeks Google sends me once a week an email that a suspicious login was prevented and I have to change the password. I use this account only for youtube-dl and its very annoying.
