Esp8266 Connection opened to ws://192.168.4.1 & CONNECTION_LOST, websocket connection lost

[ayushimundra30]

I have written a websocket code on Nodemcu 1.0 /0.9 veraion using aurdino ide and made an app ( websocket client )which connects to the websocket server on the nodemcu .It used to work, but now I am experiencing some problem.
Logs : Connection opened to ws://192.168.4.1
ECHO: successful connection
and then it auto disconnects after less than a sec
Error : saying this Close : CONNECTION_LOST, websocket connection lost
then the same thing repeats when I try to connect again

can u suggest me what the issue behind this even i tried on serial monitor / htm;l webpage same issue i am facing please suggest me how to debug this issue ??
whats wrong why its showing connection lost after a sec only when connected to client . Below u can see the attachment of code this code i flashed on Nodemcu esp8266 12-E dev board and facing this issue .
