I am trying to upload an MP4 (199MB) file to my "/static/video" folder for an existing django project, using the pythonanywhere file upload interface. Within 10 seconds of initiating the upload my connection crashes with a "Secure Connection Failed" error (connection to the page was reset while the page was loading, page you are trying to view cannot be shown because the authenticity of the received data could not be verified, please contact the website owners to inform them of this problem)
I am using Mozilla Firefox 55.0.3, if that sheds any light on the issue. I have a 1GB quota on PythonAnywhere, of which only 16% (162.7MB) has been used, so presumably this is not a space or filesize issue.
Any ideas or suggestions would be greatly appreciated.
