Unauthorized Access message when browsing snapshots from a Linked Jira Instance

Symptoms:

The following message is displayed when browsing Linked JIRA instances:

Open

Cause:

When using oauth without impersonation, you need to authenticate in the remote application.

Resolution:

To authenticate, go to your user profile or some dashboard with the Activity Stream gadget and click Authenticate with <...>

Open

Corner case:

Sometimes that authorization window is not present at all and you may need to whitelist the Jira instances.

1. Go to Systems - Security - Whitelist

2. Add a new record in the whitelist table with the following values

   1. Expression = domain of the other Jira in the following format "https://{domain}/*"(don't forget the /* at the end)

   2. Type = Wildcard expression

   3. Allow incoming = true
      
      

      Open

      

3. Repeat steps 1) and 2) on a second instance

4. Recreate application links
   
   Now, in both Activity streams you can see authentication windows.
   Keep in mind, that its necessary to authorize the connector in both instances (both activity streams).
