Unknown Host Exception While running elasticsearch using docker-compose on Mac

Elastic Stack Elasticsearch
1

Hello all,

I am pretty new to elasticsearch & docker. I am trying to deploy my application using docker-compose. It seemed to be working fine on Windows. Suddenly, I am facing following issue on Mac Os.
My search-labels application is not able to connect to elasticsearch. It works for a while if I clear ./var/ & start application with sudo. But after sometime it again throws same error. I have tried searching on web & followed posts related to this. But not able to figure out. Please suggest a solution.
