I am in the second round of a game jam (20 hours left).  I have been exporting and uploading my game from Construct 3 as an HTML 5 Zip without any issues for days.  But suddenly today, it fails every time with the error message: "There was a problem completing your upload."

I have tried creating a brand new project page and even creating a new one page project (for testing).  But, whatever I upload gets the error message right away.  There are no details on why it's erroring out.

Does anyone have any suggestions on what I can do to fix this?

EDIT: After more testing I was able to upload the same export file from a PC (I normally work on an Apple Laptop with Safari), so the problem seems to lie there.

For some reason I'm running into the same issue myself today, getting the 'There was a problem completing your upload' message.  I was trying to upload the latest updates for my game demo, but can't for whatever reason.

Never mind.  I was able to upload things through Dropbox.

Do You Find A Solution This Happened To Me Can't Upload Any Games Yet
