When trying to upload a picture using Quick App qMedia View web part  displays an error page “Internet Explorer cannot display the webpage”. You get this error after clicking on the “Checkin” Button in the web part .But Once we get back to the page where the web part is added the Picture is getting uploaded and displayed in the MediaView Web part.

The web part is working fine when added in SharePoint sites which are redirecting to the default port, however, if it is added in any other sites which are redirecting to any other port you get the error page.
