ESP8266 internet connected switch Stop working

Debug is commented, sorry I am not used this node mcu

How this MQTT library must be installed?
I think that the problem is, I copied this new "MQTT client library" to Arduino Library folder.
Why in MQTT_Libray is two times mqtt.h?

/Libraries/ esp-mqtt / src
and
/Libraries/ esp-mqtt / src / mqtt

Hi..i am a new user here. I faced the same problem, but i followed the same as suggested above, I used the new libraries and found them working fine for me. You must try them with the way as suggested. If again you will face the problem then please share some more details.

Could you show files in esp-mqtt library?

This is contents from " Arduino \ Libraries \ esp-mqtt " folder
Now I use 1.6.10 version from Arduino but relay switch is not work
