症状

Confluence will display a warning box saying 'Error(s) Occurred - Bad Request' and will continuously prompt for a Time Zone when viewing a page with an embedded Team Calendars for Confluence macro.

診断

This is either caused by a problem with your base URL or network interference.

ソリューション

1. Check that the base URL is configured properly
2. Ensure your proxy is properly configured: Running Confluence behind Apache

3. Try disabling any firewalls or network security to see if this is interfering. Note that Atlassian doesn't offer support for this.
