We have currently upgraded the Jira from 6.4 to 8.14. We are using CONFLUENCE version 7.3.1. Before upgradation of Jira, we were able to create the Jira task from the CONFLUENCE page without any issue.
But in jira 8.14 an error is throwing "cannot connect to this Jira server at this time" while trying to create a task directly from the confluence page.
We have checked the application link to JIRA and confluence as well which is perfectly ok. We are able to redirect to either application jira-confluence using the link.
The only issue in creating Jira task.
What could be the reason?
