I have set up my new SharePoint 2019 environment and created a site collection and web application. But as soon as I join in, a popup appears asking for my credentials and it keeps asking, as shown in the following image:

DisableLoopbackCheck  - Unauthorized credentials

 

  • I'm sure I entered the right credentials.
  • Trying to login by the Farm Account, and site collection administrator.
