Hey, I am testing okta with [asp.net](http://asp.net) core mvc, target framework .net 6.0. The sample works fine when running local on iisexpress or kertrel webserver.  
Example: running locally the application url is https localhost:7173. The Sign-in redirect URIs in okta is [https://localhost:7173/authorization-code/callback](https://localhost:7173/authorization-code/callback). This works fine.  
But If I publish this project and put it in IIS in a virtual directory called testokta. The application url will be [http://localhost/testokta/](http://localhost/testokta/) okta redirect doesn’t work. I have the Sign-in redirect Uri in okta set to [http://localhost/testokta/authorization-code/callback](http://localhost/testokta/authorization-code/callback). After Authenticating when it tries to get to Sign-in redirect Uri I get 404. I have tried to set the callback option in AddOpenIdConnect as below but no success  
oidcOptions.CallbackPath = builder.Configuration[“Okta:CallBackPath”];  
I tried to set redirectUri that too no success  
oidcOptions.Events = new OpenIdConnectEvents  
{  
OnRedirectToIdentityProvider = context =\>  
{  
context.ProtocolMessage.RedirectUri = builder.Configuration[“Okta:CallBackPath”];  
return Task.FromResult(0);  
}  
My Question is, how do set the callback uri in [asp.net](http://asp.net) core mvc when the application is hosted in IIS in a virtual directory. All the example I see are running iisexpress with a portnumber not sitting behind the IIS virtual directory.  
Thanks

Hi @rrokta,

Does it work if you add the port number like [http://localhost](http://localhost):/testokta/authorization-code/callback.

Here is a blog post that could help you:

No adding the portnumber doesn’t work.

Hi @rrokta,

Do you see any error in your system logs in Okta when you are redirected to your virtual path?
