Can't connect NodeMCU with MQTT

[sivanath]

@swalahamani @salmanfaris
I changed my conf file and specified ipv4
And this is the status of the port (from resource monitor):

Image: mosquitto.exe	
PID: 3732
Address: IPv6 loopback
Protocol: TCP
Port: 1883
Firewall Status: Allowed, not restricted

It is listening to mosquito..

@sivanath

Is it working now?

[sivanath]

@swalahamani No

[swalahamani]

@sivanath
Did you follow the steps which I mentioned previously?

[sivanath]

@swalahamani Yeah!!

[swalahamani]

@sivanath

Oh okay.

Please bring your device if you're coming for the upcoming MakerChat 0x13 tomorrow (IST). Either I and @salmanfaris or both of us will be there.

Or else we can set up a call sometime this weekend or the next week and sort it out.

Let me know.

[sivanath]

@swalahamani I may not be able to come tomorrow. I think we could set up a call. How can I contact you personally?

[salmanfaris]

@sivanath From your last message looks like the MQTT broker already running on your computer. Could you please try to do a test with nodeRED and see it's working or not.

@salmanfaris Actually, I can't connect my NodeMCU device with the localhost server. I can establish a connection using the test.mosquitto.org server.
This is my required case: YouTube link
