Error 422 and 276 when deploying a Web Application Proxy Server RRS feed

  • Question

  • Hello,

    I am trying to setup a test ADFS server environment with the goal of using federated Office 365.

    Two 2012R2 ADFS server and two 2012R2 WAP proxy server.

    the ADFS and WAP servers. I use either a domain admin or local admin of the ADFS server but it always fails with 
    the same message:

    "Unable to retrieve proxy configuration data from the Federation Server."

    On the AD FS WAP server the event logs event 422:
    Trust Certificate Thumbprint: 
    Status Code: 
    Exception details: 
    System.Net.WebException: The remote server returned an error: (401) Unauthorized.
       at System.Net.HttpWebRequest.GetResponse()
       at Microsoft.IdentityServer.Management.Proxy.StsConfigurationProvider.GetStsProxyConfiguration()

    at the same time the event log on the ADFS server it is trying to trust with comes up with event id 276.

    Note : I re-configure the WAP mannualy every two day to make sure the certificate is renewed. and on the WAP server – I get the application event log entries every minute saying that the WAP server successfully retrieved its configuration?

    How can I fix this ?

    Thnak's for your help.
