Python requests.exceptions.ConnectionError

I have the python script which crashes after the second alarm would be triggered. So when the first fault occurs the phone call happens. But when the second call would be triggerd the script crashes. The script will wait for the GPIO to be high and then will make a phone call to alert that there is a problem with the machine.

#!/usr/bin/env python3
#coding: utf8

import os
from os.path import join, dirname
from pprint import pprint
import vonage
import RPi.GPIO as GPIO
import time, datetime


client = vonage.Client(
    application_id="XXXXXXX",
    private_key="XXXXXX",

voice = vonage.Voice(client)

GPIO.setmode(GPIO.BOARD)

GPIO.setup(18, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)

################################### MAIN ##################################
  
  def call1():
    response = voice.create_call({

        'to': [{'type': 'phone', 'number': "XXXXX"}],
        'from': {'type': 'phone', 'number': "XXXXX"},
        'ncco': [{'action': 'talk','text': 'Störung Heizomat erkannt!',"language": "de-DE","style": 6 },]})

while True:
    if GPIO.input(18) == GPIO.HIGH:
        time.sleep (15)
        if GPIO.input(18) == GPIO.HIGH:
            make_call = call1()
            while GPIO.input(18) == GPIO.HIGH:
                time.sleep(60)
    time.sleep (5)

Do you have any idea, why this happens?

Thanks in advance! Philipp

If you just google what „Connection reset by peer“ you what happened. It‘s very simple, your connection was closed by the server you‘re connecting to. You‘re waiting too long for the server, so it‘s closing your connection because you timed out

I didn‘t watch the vonage API docs for long, but you should think of creating the client instance in the if where you do want to create a call.

#!/usr/bin/env python3
#coding: utf8

import os
from os.path import join, dirname
from pprint import pprint
import vonage
import RPi.GPIO as GPIO
import time, datetime

GPIO.setmode(GPIO.BOARD)

GPIO.setup(18, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)

################################### MAIN ##################################
def call1():
    response = voice.create_call({

        'to': [{'type': 'phone', 'number': "XXXXX"}],
        'from': {'type': 'phone', 'number': "XXXXX"},
        'ncco': [{'action': 'talk','text': 'Störung Heizomat erkannt!',"language": "de-DE","style": 6 },]})

while True:
    if GPIO.input(18) == GPIO.HIGH:
        time.sleep (15)
        if GPIO.input(18) == GPIO.HIGH:
            client = vonage.Client(
                application_id="XXXXXXX",
                private_key="XXXXXX",
            )

            voice = vonage.Voice(client)
            make_call = call1()
            while GPIO.input(18) == GPIO.HIGH:
                time.sleep(60)
    time.sleep (5)

If I didn‘t do a typo that should work for you
