Not working Gadget on the Confluence

[Andrian Limanski]

Hello everyone.
I have Confluence and Jira for Server edition.
I made a copy of the Confluence, replaced Server ID, installed a trial license, made a new SEN number.
On a page from copy Confluence installed "Two Dimensional Statistics" Gadget and the data from it is not loaded, in the browser console the request for the gadget has a 500 error: java.lang.NullPointerException at com.atlassian.gadgets.renderer.internal.http.TrustedAppContentFetcherFactory.createCertificate(TrustedAppContentFetcherFactory.java:59)
Everything works on the original Confluence. Both Confluence's connect to the same Jira.
Where is problem?
