When creating a new Application Link an Error banner is displayed behind the Application Link modal. The modal does not go away until you click Cancel.

As illustrated in the screenshot:


Diagnostic Steps

  • To better understand why the link does not get created successfully, we can use the browser's developer tools.
  • The HAR File shows us the response is 401 Unauthorized 

  • With the use of Applinks Diagnostics Plugin we can further diagnose why the Application Link fails to create. In this example you'll see the echo response test is failing:

    HTTP Echo: fail
    Request URL is inconsistent. Sent
    Echo response is inconsistent with request
    Authentication Check: warn
    Server date: Mon, 18 May 2015 01:36:19 GMT
    Attempting authentication of link to Stash
    Checking if OAuthAuthenticationProvider is
    OAuthAuthenticationProvider is configured for
    Stash, trying authentication
    Attempting to request
    OAuthAuthenticationProvider Failed to get token
    from service provider, problem was: 'signature_invalid'
    Failed to connect using
    OAuthAuthenticationProvider to Stash
  • By comparing a HAR file and results of the Application Diagnostics you'll see that there is a problem with authentication.


  • One of the applications is accessed through a reverse proxy, while the other one is not. 


  • Bypass the proxy on both sides and try creating the Application Link again.

(info) You can bypass a proxy by setting up a second connector in Tomcat to be used specifically for the application link. For more details take a look at Step 1.3 of Integrating JIRA with Apache
