Confluence is running on our Intranet with version 5.6.6. I successfully installed the HipChat add-on plus signed up and created a group on the HipChat site. When I try to preform the integration from our Confluence server I get the error.
Unable to install integration
The value must be an absolute URL
As a test I also setup the add-on with our JIRA instance and tried to integrate it and received the same error as well. I'm wondering if it is because our Confluence/JIRA instances are only internally accessible and have no external access?
