Hello! Recently, I was trying to upload my game on itch (to test if it works), but instead of uploading, it gives an error message:
 There was a problem completing your upload.

This happened every time I tried to upload and I'm not sure why this happens. I'm pretty certain that there's no problem with what I uploaded as it was a zip file with only two files inside, a ttf for formatting and an index.html for the game.

And also, there's a similar issue with uploading the cover image for my game, the error message is as follows:

There's an issue with the file you selected

Please edit your image or try another one

• Server failed to respond, please try again later

The image is within reasonable size, is there any way to fix this?
