Export game - doesnt work most of the time (indie sub)

I bought the indie subscription, and after that this happens all the time. I get this message all the time when exporting, and sometimes it will work to export. But more times i get this screen. And its really frustrating because remaining builds goes also down, everytime i get this message. While i cant download the game.

Strange. How long has this been happening? Days? Weeks?
Can you confirm the size of your .json file, the size of your whole project’s folder, and your actual Internet speed (download and upload)?
