Hi There

We have a .net core application when we deploy to our dev server gives error below:

===================================================
Category: Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware
EventId: 3
RequestId: 80000b02-0000-e400-b63f-84710c7967bb

Failed to determine the https port for redirect.

Any help would be appreciated.
Thank You and stay safe

Hi,

According to the error message, I guess you used HttpsRedirection middleware in your application. It seems that you missed setting the https binding for your asp.net core application.

The HttpsRedirection middleware will check if you have set the https binding for your application.

Since I don’t know how you host your application in your server, I suggest you could try to comment out the app.UseHttpsRedirection(); in your application and deploy again, this may solve your issue.

If you still want to use https in your application, I suggest you could follow below article to set the https bindings.

Kestrel server: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/servers/kestrel?view=aspnetcore-5.0#configureiconfiguration

IIS: https://support.microsoft.com/en-us/help/324069/how-to-set-up-an-https-service-in-iis

Bests,
