I have Jira and Confluence installed on same server on centos 7.4 virtual-machine.
I have Jira installed behind nginx for https access while Confluence is not but that can change in future. I did import SSL cert (and CA bundle) that I am using for Jira using /opt/atliassian/confluence/jre/bin/keytool and it was successful.
But I still don't have working application links between Jira and Confluence.
Please note here that I don't know what to enter for:
Consumer Key, Shared Secret or Public Key fields during the integration.
P.S: I am using Jira v7.10 and Confluence v6.9;
