How to setup identityserver4 on IISExpress?

[stephyap]

This is my appsettings.json in my asp.netcore3.1 Api:

When I run the Api it gives me the error:
Document

	Name	Value	Type
	disco.Error	"Error connecting to https://localhost:80/.well-known/openid-configuration. The SSL connection could not be established, see inner exception.."	string

It seems that the AuthConfig Endpoint port localhost:80 does not run on my IIS Express.

I don't know how to run this port on IIS Express. Please help.

It's been years, but I vaguely recall that when I first setup VS2019 and try to create web based project, it asked me about installing a developer self-signed certificate on the machine as well as switching Windows 10 over into Developer Mode. Did you do these steps?

Thanks for the reply @Skydiver . Actually this is a source code from azure which I need to run on my local machine. I did not do the steps that you mentioned above. The documentation tells me this:

I already installed the devcert.pfx on my machine though.

As a quick aside, HTTPS runs on port 443, but in your OP you mentioned port 80.

Still I got an error after changing it on port 443:

Well at this point it time to check the obvious.

Does the directory ". well-known" exist? Does the file "openid-configuration" exist?

If neither physically exist, is there code in that library you are using that detects that URL is requested and returns a response for it? Is that code being hit?

When I build the Api there are no errors:

This is my launchsettings.json:

I already tested IdentityServer4 implementation based on their documentation, In this case it seems like my AuthConfig(localhost:8080) or IdentityServer is not running inside my IIS Express web server and im running out of ideas how to run my IdentityServer.
