Pytube age restricted, and can't be accessed without logging in

Question

I'm trying download a video from YouTube by pytube but it throws this error below:

url_youtube age restricted, and can't be accessed without logging in.

Some posts says to open pytube -> innertube.py and change the line 223:

def __init__(self, client='ANDROID_MUSIC', use_oauth=False, allow_cache=True)

to:

def __init__(self, client='ANDROID', use_oauth=False, allow_cache=True)

I did it but throws another error:

HTTP Error 400: Bad Request.

What can I do?
