"No Confluence page found with the given URL." in latest Jira (7.12.3)

[AENSys Informatics Ltd.]

Hello,

We use the latest Jira (7.12.3) with old Confluence (5.3.1). We get an error message "No Confluence page found with the given URL." in mentioned in section (see the image below) and confluence pages have no preview. I added "/display" to Trusted application URL path, but did not help. We have haproxy front of confluence and jira too.

Could you help me, please?

Kind Regards,

I use user directory, so confluence users authenticate from jira and I have system-administrator access both site.

Ok, that means your Jira user doesn't have access to the Confluence page, so it can't pull information about it.

I landed on confluence login page. The links works very well, but I would like to get a preview from Jira and if I login to confluence i'm on the right confluence page.

What happens if you log out of Confluence, go to this Jira, copy one of the links behind one of the "page" links, then paste the link into a browser?
