JIRA application cannot reach Confluence application when creating an application link between the two. An error message is shown:

診断

Verify the connectivity between both servers. That can be done using the following methods:

• Ping
• Tracert
• Wget
• cURL

考えられる原因

1. Wrong Reciprocal Link URL. This is the url that the remote application (JIRA) uses to make the connection back to the local application (Confluence). 
2. Problem trying to reach out to the other server
   
3. Blocked connection

ソリューション

• Contact your Network Administrator and perform network tests in order to see what connectivity errors (if any) are blocking the connection between both servers
• Check the Reciprocal Link URL to see if it matches what the remote application has when performing the connection
