BriniM commented 4 years ago

Can confirm, same issue here with 1.9.6.

ArthurGarnier commented 4 years ago

Same here, tried versions 1.9.{5,6,7}.

trangcongloc commented 4 years ago

I have the same issue recently. In my case the issue only appear when using different user_agent

Working code

from fbchat import Client

client = Client("email", "pswd")

Error code

from fbchat import Client

USER_AGENT = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36"

client = Client("email", "pswd", user_agent=USER_AGENT)

you must delete client.logout(), it work for me

SDS-2704 commented 3 years ago

I am facing the same error while trying to log-in to fbchat.Client. This is obviously despite me entering absolutely correct ID & P/W. It could be because of any latest update in the package, or a user_agent / session (cookies) issue too. Prima-facie, if you think a few adjustments need to be made in the client or state file/s, please let me know, else I shall share the complete code link for your perusal.

Below's the error message. I will be highly grateful, if I can get an idea of where am I going wrong?

The same here. Started a couple of days ago and no changes in code was done. It "just happened". Someone please help as I'm lost here. The same stuff happens with my "real" code: Example code debug log:

ArthurGarnier commented 3 years ago

I'm trying to figure out what is happening.

In fact in _state.py ; from_session method a "get" on facebook.com return a 200 response but with empty content (Content-Length = 0) : This is not a normal thing, Facebook should return the home page with the login fields.

adns44 commented 3 years ago

I experience this problem too. It started at yesterday evening and my account blocked, Facebook asks my phone number and a picture from me.

ghost commented 3 years ago

I don't know about you guys, but switching back to "old" facebook fixed it for me.

How do you do that?

ArthurGarnier commented 3 years ago

Can confirm it works with the old facebook... Hope an update soon to support the new one.

You can do that by passing an OLD user agent : client = Client(login, password, user_agent="Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko")

The same problem is happening for me. I think the html was changed and the regex is not working now. Any updates coming soon? I'm still unable to log in, since facebook made the new mode permanent. If there is anything I could help with I would be glad to.
