esp8266: [Errno 103] ECONNABORTED after some time

I can't get behind the following issue:

I run this script:

import network
from time import sleep
from urllib.urequest import urlopen
import json

wifiap = network.WLAN(network.AP_IF)
wifiap.active(False)
routercon = network.WLAN(network.STA_IF)
routercon.active(True)
routercon.ifconfig(('10.0.0.128','255.255.255.0','10.0.0.138','10.0.0.138'))
routercon.connect('mywifi', '123')
while not routercon.isconnected():
    pass

posturl=('http://10.0.0.156:23102/rest/v2/send')

adc = machine.ADC(0)
gc.enable()

while True:
    value = adc.read()
    if value < 200:
       message = {'username': 'test', 'message': value, 'chatid': 'test', 'password': 'test', 'notifyself': 'false'}
       r = urlopen(posturl, data=json.dumps(message).encode())
       r.close()
    gc.collect()
    sleep(1)

And after some period of time it errors with ECONNABORTED.
It usually happens when the "urlopen" line has not been executed for a while.

When this happens I can't do http posts to this endpoint anymore
r = urlopen(posturl, data=json.dumps(message).encode())

however if I use the domain pointing to the same webservice instead it starts to work again:

r = urlopen("http://webservice.ddns.net:23102/rest/v2/send", data=json.dumps(message).encode())

How can I solve this issue permanently without reseting the board each time?

OSError: [Errno 103] ECONNABORTED

closedby Javier96Barreraopened 2017-10-11updated 2017-10-13

Hi, I'm quite new to micropython. I have flashed the 1.9.2 version on my Lolin v3 (Nodemcu 12e).
I load the code using ampy command, then open terminal with Putty, and reset the board. i get this error while trying to use the sentence "connect()":

Traceback (most recent call last):
File "main.py", line 44, in <module>
File "umqtt/simple.py", line 56, in connect
OSError: [Errno 103] ECONNABORTED

MicroPython v1.9.2-8-gbf8f45cf on 2017-08-23; ESP module with ESP8266

from umqtt.robust import MQTTClient

#DHT PIN
d = dht.DHT11(machine.Pin(14))

gc.enable()


def do_connect():
    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    if not wlan.isconnected():
        print('connecting to network...')
        wlan.connect('SSID', 'PASSWORD')
        while not wlan.isconnected():
            pass
    print('network config:', wlan.ifconfig())


for i in range(20):
    do_connect()
    thingspeakChannelId = "MyChannelID"  # Thingspeak Channel ID
    thingspeakChannelWriteapi = "MyWriteKey"  # Write API Key
    myMqttClient = "esp8266_mp"  
    thingspeakIoUrl = "mqtt.thingspeak.com"
    publishPeriodInSec = 15
    print("Control 1")
    c = MQTTClient(myMqttClient, thingspeakIoUrl, 1883)

    print("Control 5")
    c.connect() #HERE
    print("Control 6")
    c.publish(credentials, payload)
    print("Control 7")
    for i in range(5):
        led.low()
        time.sleep(0.05)
        led.high()
        time.sleep(0.05)
    print("Sending data...", gc.mem_free())
    time.sleep(publishPeriodInSec)

    c.disconnect()
machine.reset()

Thanks for your time, if there is any problem regarding the information or post structure, tell me and I will try to fix it.

This github issue tracker is mainly for bug reports and code improvements. The report here is more of a problem using the libraries, and help in this area is best asked at https://forum.micropython.org. So please try to ask your question there (or maybe someone had the same issue and already fixed it).

Otherwise, the general thing to try is to verify you have internet connectivity, eg:

>>> import socket
>>> socket.getaddrinfo('micropython.org', 80)

Thank you for the reply, I will move this question right now. PS: I checked and yes, i got internet connectivity. Reply: [(2, 1, 0, '', ('176.58.119.26', 80))]
