If I enter a correct username and password (I tried 4 personal account), this will happen. If I put wrong credential, it works normally. Before today, everything was fine. now, I am facing with this error without make any changes in my code.

Hey @md4956 I am facing same issue. Have you resolve this problem ?

[md4956]

Hi @ghyath5

With this repository's solutions, no. I've fixed it by creating a multi-thread process, using another library.

You can pass is_threaded=True to bot.login() to avoid this issue.

From bot.login():

        if "is_threaded" in args:
            if args["is_threaded"]:
                return True
        signal.signal(signal.SIGTERM, self.print_counters)
