Cant Login since morning!

[ambit0]

I'm getting error:
fbchat._exception.FBchatUserError: Login failed. Check email/password. (Failed on url: https://m.facebook.com/cookie/consent-page/?next_uri=https%3A%2F%2Fm.facebook.com%2Fhome.php%3Frefsrc%3Dhttps%253A%252F%252Fwww.facebook.com%252F&_rdr)

[m-el-azzouzi]

Check the location of the file _state.py (written in the Exception) then edit it and go to login function (around line 126), scroll to line: r = session.post("https://m.facebook.com/login.php?login_attempt=1", data=data) (line 139 for me).

Paste that after this line (with correct indentation):

if "cookie" in r.url:
    beg = r.text.find("action=")+8
    end = r.text.find("\"", beg)
    urlCookies = "https://m.facebook.com" + r.text[beg:end]
    payload = {i["name"]:i["value"] for i in find_input_fields(r.text).find_all('input')}
    r = session.post(urlCookies, data=payload)

I used it, but now i have error:

Ok, do you have some more logs? It seems it's something with your config, not fbchat
Try print(r.text) before line 196 and paste what it prints

I had a similar issue, I used fbchat._state.FB_DTSG_REGEX = re.compile(r'"token":"(.*?)"') to solve it but I don't think it will work for you from your output....

[orzechszek]

if "cookie" in r.url:
beg = r.text.find("action=")+8
end = r.text.find(""", beg)
urlCookies = "https://m.facebook.com" + r.text[beg:end]
payload = {i["name"]:i["value"] for i in find_input_fields(r.text).find_all('input')}
r = session.post(urlCookies, data=payload)

If it works, please also update in v1 project - fbchat 1.9.7 available through pip.
