Cant Integrate Confluence with Jira

Question

Hi All,

Can someone please help me with ideas to solve this problem. May be Permission related but I created both the space in Confluence and the project in jira. We ahve the cloud premium version etc. Maybe I need some higher permission not sure.

In confluence when I click Space settings and integrate and want to select

ADD and Select "Jira system" the pop up oens and loads but siplay this message:

"Sorry, there are no links for this user available, check your permission configuration of the remote application."

Thus I cannot serach for my jira projects or anything ? 
What is the issue here ?

@Johan Ekman you could link your jira to your confluence using the link:

https://YOURDOMAIN.atlassian.net/wiki/plugins/servlet/applinks/listApplicationLinks

But in my opinion, I think that you have export all spaces on your confluence only site and import them to your jira site.

The original reason why this happened is unknown. 
Is it "easy" / possible to merge both instances together or connect them ?

These are two different instances you have there. Is there a reason to have two different instances? You can have jira and confluence to either "name"jira.atlassian.net or "name"confluence.atlassian.net
