Hi, This error is caused due to low memory available.

@b4sudhir , as @sanketwadekar mentioned, this error could be caused by memory issues, but can you clarify what exactly are you trying to do? The error I see here is for MQTT. Which webserver are you trying to connect to here?

@sanketwadekar > Hi, This error is caused due to low memory available.

Details for free available memory with time stamp, just before device tried to make connection for MQTT.

@shahpiyushv I am trying to add webserver with websocket. Libraray which i used is given below. I want to run local webserver on my device for offline use. First i tied to add webserver in which i didnt get any error, After that i tried with adding websocket in it and start getting error while connecting . In Mobile App also Confirming Node Association Failed.

And i an using this lib in my many projects with MQTT without any problem .

include //(DEFAULT)// Arduino15\packages\esp32\hardware\esp32\2.0.5\libraries\WebServer\src\WebServer.h

WebServer server(80); //LIBRARY FOR WEBSOCKETS

include //https://github.com/gilmaimon/ArduinoWebsockets

WebSocketsServer webSocket = WebSocketsServer(88);

@shahpiyushv .If i remove websocket than my system work perfectly without issue . So it might conflict in library with websocket. Now i removed websocket from my project and using ajax ...My system is working flawlessly. Thanks for your support and guidance.

@b4sudhir , probably the websocket library is using more heap memory causing the low memory issues for MQTT. Anyways, closing this since it has been resolved.
