Hey guys, so I was wondering why can't I upload any mods ?
When I try with the tools "The Binding of Isaac: Afterbirth+ Mod Uploader", I choose my metadata.xml and it say:

Processing 'NAMEOFTHEMOD/metadata.xml'... Success
Ready to upload mod 'NAMEOFTHEMOD'

But when I use the upload button, it stop at 24%, then it say:

Failed to upload mod 'NAMEOFTHEMOD': Error (2) - Unknown error

I googled it but I can't find anyone who solved the bug. Often discussions on this subject only consist of the question, and sometimes a "same"...

I tried a hundred times and It """worked""" 3 times, but the mods on my workshop are empty (0.000 MB) and have no name, description or preview images.

Any ideas ?
