httpgd plot viewer fail in remote server

[QiangShiPKU]

Describe the bug
When I press 'Enter & Command', R code can be run in R terminal. However, when I try plotting, httpgd plot viewer can open, showing "Status: 404 Reason: Not Found". By clicking "Open in External Browser" button, I can see the plot.

To Reproduce
see above and screenshot

May be duplicate of #916, #923.

Please try update the httpgd package.

Yes, installing the latest release of httpgd should resolve this.
