How to deploy ASP.NET Core application?

I created a sample ASP.NET Core Web API application with MondoDB following these tutorials

  1. [Using MongoDB .NET Driver with .NET Core WebAPI] (
  2. Publish to a Linux Production Environment
  3. Publishing an ASP.NET Core website to a cheap Linux VM host

Excited about the prospect of deploying an ASP.NET application in a Linux environment, i got the $5 plan and installed Ubuntu.

I have been successful in running the application and nginx locally with the application listening @ port 5000. However, i’m unable to access my application from outside. I’m getting the ‘502 bad gateway’ error.

Could anyone with experience on the above stack help me out? Thanks for your time.

A 502 error usually means one of two things.

1.) Your application is not listening locally as expected on http://localhost:5123

Test this by using wget/curl or telnet to open the service from from your ssh session on the server and make sure it responds. If it’s not, try restarting supervisor.

2.) Your nginx configuration is not correct.

Share your nginx configuration here and we can take a look at it.
