Welcome to the Alteryx Knowledge Base

Issue:

When attempting to save a workflow to the Gallery or access the Gallery via FQDN (e.g., ayx.domain.com) or IP in the browser, you are continuously prompted for Windows credentials. This article refers to situations where this behavior occurs ONLY on the Server machine itself; but you are able to access Gallery and save workflows from remote machines using the same credentials.

Environment:

• Alteryx Server
  • Windows Authentication enabled
    
    
    

Diagnosis:

To ensure this issue is isolated to the Server machine, verify that you can access the Gallery via FQDN or IP in the browser and save a workflow to the Gallery from other machines (not the Server) with the same credentials.

Additionally, you should be able to access Gallery via the Server machine using "localhost".

Cause:

Certain versions of Windows include a security feature called loopback check functionality.

Resolution:

1. Follow the instructions from this Microsoft KB article and choose either Method 1 (recommended) or Method 2:
   • Method 1: Create the Local Security Authority host names that can be referenced in an NTLM authentication request
   • Method 2: Disable the authentication loopback check

• Error message when you try to access a server locally by using its FQDN or its CNAME alias
