Description

This is currently simply raised as ExtractorError which causes youtube-dl to include the text to report it as bug. Either the ExtractorError message should be changed to explain that it should only be reported if it's actually working e.g. in the browser without password before recommending to report it as bug or the way this type of error is handled should be changed.
