Thank you for your react , there is the message displayed on the console :

Traceback (most recent call last):
File "<stdin>", line 89, in <module>
File "umqtt.py", line 173, in wait_msg
OSError: -1

@YazIdo said in OSError: -1:

line 173

please put some lines e.g. no 168..180 from your umqtt.py
and mark which is 173

This is happening:

if res == b"":
            raise OSError(-1)

The response is empty...
Response is res = self.sock.read(1)

@yazido Do not use "keepalive" in function MQTTClient.

Examle:
c = MQTTClient("ESPython", "192.168.0.21", port=1883, user="user", password="pass", keepalive=0)
or
c = MQTTClient("ESPython", "192.168.0.21", port=1883, user="user", password="pass")
