Login with session, better code?

[BaGRoS]

I use this code for login before post:

`def login_user(username, password, session_file="session.json"):
cl = Client()
max_attempts = 5
session_file_path = Path(session_file)

if os.path.exists(session_file_path):
    for attempt in range(1, max_attempts + 1):
        cl.load_settings(session_file_path)
        try:
            cl.get_timeline_feed()  # Check if the session is valid
            print("Session is valid, login with session")
            telegram_message_instagram("Session is valid, login with session")
            break
        except Exception as e:
            print(f"Session is invalid (attempt {attempt}): {e}")
            telegram_message_instagram(f"Session is invalid (attempt {attempt}): {e}")
            if attempt < max_attempts:
                print(f"Waiting 1 minute before trying again (attempt {attempt})")
                telegram_message_instagram(f"Waiting 1 minute before trying again (attempt {attempt})")
                pause("Wait after problem with session ...", 60)  # Wait for 1 minute
            else:
                print("All attempts failed, removing session file and logging in with username and password")
                telegram_message_instagram("All attempts failed, removing session file and logging in with "
                                           "username and password")
                os.remove(session_file_path)
                cl.login(username, password)
                cl.dump_settings(session_file_path)
                print("Session saved to file")
                telegram_message_instagram("Session saved to file")
else:
    cl.login(username, password)
    print("Login with username and password")
    telegram_message_instagram("Login with username and password")
    cl.dump_settings(session_file_path)
    print("Session saved to file")
    telegram_message_instagram("Session saved to file")

user_id = cl.user_id
return cl, user_id`

and its working, few day... Later can't login, when I delete manually session file, again can login, post image, but can't post comment to this immage, needs "login with password" or something similar...
This code for login looks good?

When there is a session settings and we try to load the settings and try to login again, what is going under the hood? Is it try to login again to the Instagram or something else?
