Hey there, mod uploads should work fine at the moment. From where in the world are you trying to upload? Feel free to email the errors in your browsers network console to support@factorio.com so I can take a closer look.

Can you try uploading from a different device and/or internet connection?

The CORS error in the logs is misleading. It just pop ups because something closes the connection of the actual file upload. Also please don't upload screenshots of your network logs in this public forum, there's a chance they contain sensitive session keys for your account.

Seems like you're running into the same limitation as viewtopic.php?t=130952 But it'll take a while to fix.

Set up the uploader service on a different provider which might help with your issue. Can you please try again?
