WebApp seach flights issue

Hi, I have deployed your application but the search is not working. The application continuously throws an error **"Firefox can’t establish a connection to the server at ws://webapp.vnet:5000/gql-ws.".** can you please help me in resolving this or let me know if I'm missing anything, as i am new to docker environment. I have checked in the port no. :5000 there is nothing deployed in it.
