One IIS server ask credentials other accept windows authentication

Hi,

Any advises how to troubleshoot the authentication issue on the IIS (W2012R2). In my mind I have two servers with equal setup, but one server does handle the windows authentication (?) correctly. When going to URL:

workingServerA.domain.com/folder/app.svc

Then I have another server with the same URL:

failingServerB.domain.com/folder/app.svc

It is asking the user ID and password.

Wish to learn how I could troubleshoot this.

Browsers: Chrome, Edge, and IE tested: same behaviour.

Servers are domain memembers. Workstation is domain member, and my account is domain account.
