Pi zero on blink-lib python won't connected

Solved
1

Hello,
I am using blink-lib python library from official git here and I am following someone’s tutorial’s here but due to there’s no option for raspberry pi zero so I choose generic board with ethernet connection. even though I am using same smartphone for tethering pi zero and controlling blink app, my blink-app says “wasn’t connected yet”.
I am sure my token is correct, pi zero has internet connection by tether, and blink library is installed (showed up blink ascii logo when running)

here’s my script:

import RPi.GPIO as GPIO
import blynklib
import time

GPIO.setmode(GPIO.BCM)

GPIO.setwarnings(False)

GPIO.setup(11, GPIO.OUT)

p=GPIO.PWM(11, 50)

p.start(7.5)

auth_token= 'my token was here...'

#Initialize blynk

blynk = blynklib.Blynk(auth_token)

@blynk.handle_event('write V0')

def write_handler_pin_handler(pin, value):

    Doorlock = (format(value[0]))

    if Doorlock =="0":

        p.ChangeDutyCycle(12.5)

        print("Door Locked")

    elif Doorlock =="1":

        p.ChangeDutyCycle(7.5)

        print("Door Unlocked")

try:

    while True:

        blynk.run()

except KeyboardInterrupt:

    print("Quit")

# Reset GPIO settings

GPIO.cleanup()

You’ve not said whether you are using the Blynk cloud or your own local server.
If it’s the Blynk cloud server and you are seeing connection attempts on port 443 then that is your problem, as the Blynk cloud servers no longer support SSL connections.

Read this for details on how to resolve the problem when using Python:

My bad, yes it is blynk cloud server.
I don’t see “connection attempts to 443”, it just blynk ascii and my blink cursor. So I am not sure it was connected to that port.

Update: now it’s connected, since I disconnect my phone from my home wifi. But it’s strange because AFAIK blynk is using websocket but why sharing my phone connection and my phone also using shared connection by wifi caused failed to connect? I’ve got this problem when I am working my own socket coding, it’s works on same network but not when trying to different network (error 10040 winsock)
