...Cause
The tool needs to connect to https://confluence.atlassian.com in order to retrieve information about KB articles and other relevant information. If this website is not accessible by the application, log scan will fail.
Some reasons include:
- https://confluence.atlassian.com might be temporarily unavailable.
- The application might not have access to the Internet.
There's an open feature request to allow the log analyzer to work even when https://confluence.atlassian.com is inaccessible, available here: Unable to locate Jira server for this macro. It may be due to Application Link configuration.
Resolution
Make sure https://confluence.atlassian.com/ is accessible by the application. The utility HttpClientTest can be used for that.
