Telethon: The phone code entered was invalid... but it should be valid

Hello, I’m trying to implement an automatic account-creation system using smspva API to generate Phone Numbers and get SMS. I’ve coded everything, and smspva seems to work:

I get the phone number and then:

client = TelegramClient(phone_number, api_id, api_hash) //create a session with the phone number as name (in the form +7123456789...)
assert client.connect()
client.send_code_request(phone_number) //phone number (in the form +7123456789...)

Then i place the listener to receive SMS, and I get it: code = check_sms(number_id)

I’ve printed out the code to see it was correct: Got Code: 90156

Then i just pass the code into sign_up function with this: myself = client.sign_up(phone_number, code)

And it fails:

Traceback (most recent call last):
  File "account_creator.py", line 35, in <module>
    myself = client.sign_up(number[1], code)
  File "venv/lib/python3.6/site-packages/telethon/telegram_client.py", line 468, in sign_up
    last_name=last_name
  File "venv/lib/python3.6/site-packages/telethon/telegram_bare_client.py", line 459, in __call__
    result = self._invoke(call_receive, *requests)
  File "venv/lib/python3.6/site-packages/telethon/telegram_bare_client.py", line 551, in _invoke
    raise next(x.rpc_error for x in requests if x.rpc_error)
telethon.errors.rpc_error_list.PhoneCodeInvalidError: The phone code entered was invalid 

It fails also if i replace the sign_up part with this: myself = client.sign_up(phone_number, input('Enter code:'))

If I type the code manually it still fails, but the code should be correct… as you can see:

{"response":"1","number":"123456789","id":2222260,"text":"16782","extra":"0","karma":33.975,"pass":"","sms":"16782","balanceOnPhone":0}
Got Code: 16782
Enter the Code: 16782
Traceback (most recent call last):
  File "account_creator.py", line 35, in <module>
    myself = client.sign_up(number[1], input('Enter the Code: '))

    raise next(x.rpc_error for x in requests if x.rpc_error)
telethon.errors.rpc_error_list.PhoneCodeInvalidError: The phone code entered was invalid

I have no idea what else I could try. I’m pretty new to Python. Also I’m just using all my smspva balance for testing ahahah

Thanks a lot 😃
