esp8266 gateway doesn't connect to mqtt broker

[tsunami]

Hi, I'm using ESP8266 mqtt client gateway to connect to my controller and I use cloud mqtt service. controller has connected to the broker but esp8266 doesn't connect. even it doesn't connect to the wifi and it was a access point and I've followed a topic to add a code for turn off access point. this is my code for gateway:

#define MY_DEBUG

// Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
#define MY_BAUD_RATE 9600

// Enables and select radio type (if attached)
#define MY_RADIO_NRF24


#define MY_GATEWAY_MQTT_CLIENT
#define MY_GATEWAY_ESP8266

// Set this node's subscribe and publish topic prefix
#define MY_MQTT_PUBLISH_TOPIC_PREFIX "mygateway1-out"
#define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "mygateway1-in"

// Set MQTT client id
#define MY_MQTT_CLIENT_ID "mysensors-1"

// Enable these if your MQTT broker requires username/password
#define MY_MQTT_USER "***********"
#define MY_MQTT_PASSWORD "**************"

// Set WIFI SSID and password
#define MY_ESP8266_SSID "*****************"
#define MY_ESP8266_PASSWORD "******************"

// Set the hostname for the WiFi Client. This is the hostname
// it will pass to the DHCP server if not static.
// #define MY_ESP8266_HOSTNAME "mqtt-sensor-gateway"

// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
#define MY_IP_ADDRESS 192,168,178,87

// If using static ip you can define Gateway and Subnet address as well
#define MY_IP_GATEWAY_ADDRESS 192,168,1,1
#define MY_IP_SUBNET_ADDRESS 255,255,255,0


//MQTT broker if using URL instead of ip address.
#define MY_CONTROLLER_URL_ADDRESS "m21.cloudmqtt.com"

// The MQTT broker port to to open
#define MY_PORT 11262

#include <ESP8266WiFi.h>
#include <MySensors.h>

void setup()
{
    // Setup locally attached sensors
}

void presentation()
{
    // Present locally attached sensors here
}

void loop()
{
    // Send locally attached sensors data here
}```

and I get this in serial:

scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 4
cnt 
271 TSM:FAIL:DIS
289 TSF:TDI:TSL

connected with Shatel, channel 1
dhcp client start...
ip:192.168.1.6,mask:255.255.255.0,gw:192.168.1.1
pm open,type:2 0
10306 TSM:FAIL:RE-INIT
10330 TSM:INIT
10351 !TSM:INIT:TSP FAIL
10377 TSM:FAIL:CNT=2
10399 TSM:FAIL:DIS
10419 TSF:TDI:TSL

anyone knows how to fix it?

@tsunami see if removing

#define MY_PORT 11262
helps. I think this define is only meant to be used when not using MY_CONTROLLER_URL_ADDRESS (but I am not entirely sure).

If that doesn't help, take a look at https://github.com/mysensors/MySensors/issues/926
It seems like the ESP8266 gateway will be unable to use DNS when using static IP configuration. In my experimental branch I have added DNS support, but it is not reliable and needs more work. You could try to use an IP address instead of m21.cloudmqtt.com - not sure if it helps but it could be worth trying.

thanks alot everything works good now and gatewat has connected to the mqtt broker. but i can't connect it to the domiticz. domoticz topics are: domoticz/in/mymqtt
but for gateway is different and i can't change for domoticz.

thank you I've done it and works great. but I found it if node is offline and I put switch on or off in controller it works but when node get connect to the controller it doesn't update switch state. how to fix it?

@tsunami program the sketch to fetch status at boot. See the first example at https://www.mysensors.org/build/dimmer for how it can be done.
