How to enable/disable HTTP/HTTPS and Change Port No in ASP.NET Core 6? (2024)

How do we enable or disable HTTP or HTTPS or change the Kestrel port number in asp.net core 6 after we run the dotnet publish? There are several ways on the internet but mainly for during development e.g.

1. Change applicationUrl and sqlPort in Properties/launchSettings.json.
2. If using Visual Studio, change in Project Properties > Debug tab > Web Server Settings.
3. Comment out app.UseHttpsRedirection(); in Program.cs and etc…

But these seems unable to work if we use dotnet publish and .NET 6. Luckily there is few settings in appsettings.json for us to solve the issue. Example settings are below:

{ "Logging": { "LogLevel": { "Default": "Information", "Microsoft.AspNetCore": "Warning" } }, "AllowedHosts": "*", "Kestrel": { "Endpoints": { "Http": { "Url": "http://localhost:5000" }, "Https": { "Url": "https://localhost:5001" } } }}

If we want to disable HTTP for the asp.net code, we just need to remove lines 11 to 13 and the same for HTTPS, if we want to disable HTTPS, just remove lines 14 to 16 and comment out app.UseHttpsRedirection(); in Program.cs.

If we want to change the port number, we just change in the Http and Https there according. By default, the port number will be 5000 for Http and 5001 for Https.

Below is an example result if disable Http and change Https port to 5005:
