I already published my application inside my ubuntu server but when I'm trying to use the command

dotnet ProjectName.dll

I got this errors. Any help?

I am confused about your setup. Did you publish an application from a windows development environment to an Ubuntu one? Also how did you publish your application(dotnet publish, publish from visual studio, etc). If so, can you first confirm that the app runs in visual studio? If you still have errors, please paste the whole exception from the server failing.
My guess is there is an issue with the dll referencing IISExpress, and on a linux environment you need to use nginx.

@jkotalik I published it on my linux machine. Yes, it's running properly on windows machine. I already fixed it by editing my Startup.cs.

@deanilvincent, what did you do to fix this?

[deanilvincent]

@jason2li Try this:

Specify a specific port by using .UserUrls("___portNumberHere___") like this:

public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseUrls("http://+:8181") // whatever port you want
                .UseStartup<Startup>()
                .Build();

I hope this helps you.
