I am working on creating a facebook app for a Magento store and listing products in facebook app.
My site is not HTTPS, but facebook app requires HTTPS, it showed "Operation timed out" error. So I disabled secured browsing option in facebook and tested in facebook appcentre. After disabled secured browsing, the site was worked well till yesterday. But today, I tried to check the output, It showing this error "The server refused the connection", even I disabled the secured browsing already.
How can I fix this error? Please look at the screenshot for clarification.
