I have issue with include canvas app into Visualforce Page. My canvas app include PHP site from my server. It works in Canvas App preview and in Chatter tab too. But in Visualforce page not.

My simple VF page


<apex:page >
 <apex:canvasApp developerName="myCanvasAppName" />


then I enter URL https:...salesforce../apex/myPage, and I got this error

Visualforce Error

Unable to retrieve installed application by namespace [null] and developer name [myCanvasAppName].


I tried to add namespacePrefix="" to canvasApp tag, but i got the same error.

Do I need something set somewhere?
