When I try to upload more than 1 file at once, only one works, the others fall in 400 Bad Request
The exact body response is :
<html> <head><title>400 Bad Request</title></head> <body bgcolor="white"> <center><h1>400 Bad Request</h1></center> <hr><center>cloudflare-nginx</center> </body> </html>
If you need to dig in the logs I tried an upload at Mon, 26 Feb 2018 18:28:32 GMT
