Function taking too long to respond: 502-Bad Gateway- The specified CGI application encountered an error and the server terminated the process.

I have recently deployed a Java Azure Function based on the documentation provided at https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-java-maven . It was working fine but the from next day (29-Apr-2018) it is taking forever to run. Every time I try to run it is giving back error 502- Bad Gateway.

I have tested the function on local using mvn azure-functions:run and it run fine.
mvn azure-functions:deploy run without any error.

We are getting 502 while testing/running the azure function on azure portal.

Could you please help me on this.
