症状

Administrator can't create new project in JIRA

診断

1. Try create project in different web browser without any Add-Ons
2. Try create project when accesing JIRA directly (eg:  bypassing webserver and network tools like SecureEntryServer(WAF))
3. Try to create project after disabling all User Plugins via Administrations > Manage Add-Ons > Enable Safe Mode and then try to reproduce the ERROR.

4. Ensure the following tomcat attributes are added in the server.xml when integrating Proxy (SSL) with JIRA server:

   scheme="https" proxyName="proxy.atlassian.com" proxyPort="PORT"
