Leaflet plot can't show in viewer window

When I write the code with leaflet package to show the plot , the plot can't be shown in the viewer window. The error message is as below:
"/session/viewhtml4bb85bf236ed/index.html?viewer_pane=1&capabilities=1&host=http%3A%2F%2F127.0.0.1%3A32275 not found"

But it can be shown in normal R with web browser.
How to solve this problems?
