MVC5

Hello,
I have created one application using angular 6 and asp.net mvc 5 and i am using crystal report 13 for displaying reports (not using crystal report viewer.)
For local server it works fine but for cloud server it does not work.

Are there any prerequisites i have to run or install on cloud server?
how to load crystal report on cloud server?
Any help would be appreciated.
Thank you in advance

What I have tried:

When i print report on local server, it gets printed. Code for local server :
reportDocument.Load("c:\\Report\\myreport.rpt");

But when i deploy my application on cloud server and try to print report, it does not get printed. I have also checked using postman but it gives result 204 no content.
I tried 2 soultions to load report on cloud
Solution 1:
reportDocument.Load(System.Web.HttpContext.Current.Server.MapPath(@"~/Report/myreport.rpt"));

Solution 2:
reportDocument.Load(System.Web.Hosting.HostingEnvironment.MapPath(@"~/Report/myreport.rpt"));

I tried these 2 solutions but no luck. Are there anything which i need to install or some setting?
