Issue Asp.net mvc 4 application on Plesk Onyx 17.5.3 is not working

[Ramkumar]

I purchased hosting space with www.bigrock.in on 1-Jan-18. I have deployed my asp.net mvc 4 application in /httpdocs folder. If i access the website it is throwing "Service Unavailable" HTTP Error 503. The service is unavailable. Please access http://www.indproperties.com/ and see the result. Bigrock support team is unable to resolve this issue till date. I am struggling with this error for the past one week. Please let me know how to resolve this issue. Please help.
