This error may due to some causes:
JIRA could be down
User may not have access to the saved filter. There is an ongoing improvement request about this: CONFSERVER-51116 - Meaningful message when there is lack of permission to view saved filter
The JQL may be pointing to projects or fields that no longer exist
Network timeout issues
JIRA is set to use a "GMT-X" timezone format using the -Duser.timezone startup parameter. This issue is being tracked here: CONFSERVER-50030 - JIRA Team Calendars unable to show in Confluence if JIRA user.timezone is set to GMT-X format
If you're using JIRA 4.4 and Team Calendars for Confluence JIRA Integration version 1.0.11, you may hitting this bug: https://ecosystem.atlassian.net/browse/JICAL-12
Resolution
Based on the four identified causes above, the corresponding suggested resolutions are as below:
Troubleshoot: Check if the JIRA service is running
Fix: Bring JIRA back up
Troubleshoot: Check the permissions on the JIRA saved filter (Get the owner of the JIRA saved filter to share it, if yet to be shared)
Fix: Ensure the viewer has permissions
Troubleshoot: Run the JQL in the issue navigator and ensure it is a valid JQL query
Fix: Edit the JIRA calendar and re-apply the new JQL query
Troubleshoot: An administrator would have to connect to the Confluence server and test the connection between it and the JIRA server
Troubleshoot: Look for the following error in the JIRA logs (

Upgrade to JIRA 5.2.x or use Team Calendars for Confluence JIRA Integration version 1.0.9 instead
