[Azure DevOps Server] TF400813: Resource not available for anonymous access. Client authentication required

| Posted in Programming

Problem:

I would like to install an agent on Windows server and connect to Azure DevOps Server. When trying to configure it , I get the error message: “TF400813: Resource not available for anonymous access. Client authentication required

Environment:

  • My TFS version: Azure DevOps Server 2019.Update1.1
  • OS: Windows Server 2016
  • Agent Version: 2.175.2

 

 

Solution:

Don’t use https://[servername]/tfs when you configure the agent. it does not work. 

When you configure the url of Azure DevOps Server, using:
https://[servername]/[organizationname]

for example: https://mydevopsserver.com/DefaultCollection

 

 

Reference:

Unable to register agent against on-premise Azure Dev Ops Server: TF400813 Resource not available for anonymous access. Client authentication required.
