You will have to try using a file storage site like Google drive or Dropbox, and link to that instead.
But do you really have to upload such a large file? A 1.2 gb blend file is quite a lot. (I would guess it is because of packed textures and/or video). You could try and remove parts of it that are really large, or compress it into a .zip which can make it quicker to upload to such a file storing site.
