Issue pushing from local to demo site

For the past couple days I’ve been trying to push a website I developed on local to a demo site using the on-board connect to flywheel utility. My website is rather large, 800mb or so, but it would be super convenient to this to work! I’ve tried pushing from my home internet, cafe internet and college internet to no avail. Below are the logs of my most recent push attempt, any idea what the 400 error means in this case?
