For some reason my tiles aren't loading, map is just showing grey. They're not being downloaded by browser and I'm not getting any error messages

The tiles are 256x256 parts of a 65409x32839 screenshot

You have to explicitly specify that your Tile Layer maxZoom option is 20, otherwise you get the default value of 18, which prevents your tiles from being called at your only zoom (20).
