Can't add link to jira issue from confluence

[Karen Tovmasian]

Hi all.

I have upgraded our confluence to 5.8.8

Our JIRA version is 6.0.6

I try to add link to issue using Link - Confluence page - search

It's asking me to authorize:

"Authorization required to create issue link. Please authenticate with Confluence."

I click authentificate and get error at new tab in Chrome

Authentication failed!
An error occurred while trying to obtain an access token. For application link "Confluence (15f07bff-ef87-3d79-829b-3dceea2e185b) https://confluence.mycompany.com com.atlassian.applinks.application.confluence.ConfluenceApplicationTypeImpl@7c1064a"

I think that this is due to difference between vesions, but i really need it working on my current version of JIRA

Can you check is it related to Permission error? I mean some special privileges might have configured for adding a link in confluence.

Thanks!
