Unable to add a jira link on a confluence site Edited

[Markus Hortig]

Hello @all

we're using Jira and Confluence in our company to organize our projects.
I've got a problem at linking a Jira-Issue on a confluence site.
I did that maybe a hundred times before at the same way but the new issues the confluence won't link it on my page but it finds it in the linking dialogue.

Do you have any idea why I'm not able to add an issue link anymore?

Kind regards
Markus
