What’s the problem? Why I receive that error message?

Reasons for 403 Error and How to Fix it

There are many factors that can cause 403 error message, the most common are:

  • You publish your site to your hosting provider, but is your host set up to look for your start page? By default, hosting provider look for index.html, index.php, index.aspx, etc, they will use it for default page. The question is what is your default page? Maybe your default page is home.aspx, hello.aspx, or something. Do you understand what I mean? So, make sure that you check you have setup your own default page correctly. Basically on control panel like Plesk, you will be able to setup your own default page or you can ask your hosting provider to setup it for you on IIS.
  • The other reason is you created ASP.NET website using one of the template in Visual Studio. If so, you might have selected a template that adds security to your page. By default, anonymous viewing isn’t allowed in some templates. This would be a setting in your config file that would need to be changed. So, to fix it, you could either read up on config settings for security or you could start over with a blank template and try publishing that.
  • Before you publish to your hosting provider, make sure that it runs locally, try just uploading simple ASP.NET Core file, so you can narrow down where the problem is
  • Make sure that your hosting provider support ASP.NET Core, this is really mandatory to run your ASP.NET Core site. If your hosting provider doesn’t support it, you need to find hosting provider that support ASP.NET Core. If you are looking for reliable ASP.NET hosting partner, check out our latest post.
