AAD Application proxy issue

문영 임 1 Reputation point

안녕하세요. AAD의 Enterprise Applications의 Application Proxy를 구성 테스트중입니다

대부분의 세팅은 완료가 되었는데요.

아래와 같이


Internal URL을 External URL로 리다이렉션 시키기 위해서 Azure DNS에서 Cname을 등록하였는데요.

ping을 해보면 Cname된 URL이 아니라 Global URL을 질의하게 됩니다.

그래서 Application Proxy 서비스에서 오류가 나고, 404페이지 에러가 나옵니다.

어떤 조치를 해야 할까요?

    Hi @문영 임 · Thank you for reaching out.

    The CName record that you have created in your DNS must point to the public/external FQDN configured in the app proxy settings. Once the Application Proxy service receives a request at the external url, it translates the url to internal url and forwards it to the server with app proxy connector installed. The connector server then forwards the request to the internal server which is hosting the web application. If you are getting 404, you need to check the logs on connector server if it is receiving the request or if there are any error while processing the request(s).

    1. Open Event Viewer and look for Application Proxy connector events in Applications and Services Logs > Microsoft > AadApplicationProxy > Connector > Admin.
    2. If needed, more detailed logs are available by turning on the Application Proxy connector session logs.
    3. Go get connector errors, you can use below command:
      Get-EventLog application –source "Microsoft AAD Application Proxy Connector" –EntryType "Error" –Newest 1
