Solution

Modifying your Communications Breakdown message

To modify the content of the existing error message, the following steps can be performed:

  1. Backup the file <Jira_INSTALL>/atlassian-jira/WEB-INF/classes/com/atlassian/jira/web/action/JiraWebActionSupport.properties

  2. Search and update the text field, which is defined after the variables in the file '<Jira_INSTALL>/atlassian-jira/WEB-INF/classes/com/atlassian/jira/web/action/JiraWebActionSupport.properties'. Eg:

    common.forms.ajax.error.dialog.heading=Communications Breakdown common.ajax.unauthorised.alert = You are not authorised to perform this operation. Please log in. common.ajax.servererror = The Jira server was contacted but has returned an error response. We are unsure of the result of this operation. common.ajax.commserror = The Jira server could not be contacted. This may be a temporary glitch or the server may be down.
  3. Restart Jira

⚠️ Since these configuration changes are performed in the Jira installation directory, any changes you make can be lost on the upgrade.
