loading fails with error 413 entity too large on PUT

This appears to be a nginx issue. There appears to be 2 parameters involved to resolve the problem :

• client_max_body_size: The maximum allowed size for a client request. If the maximum size is exceeded, then Nginx will spit out a 413 error or Request Entity Too Large.
• client_body_timeout

@jaxoncreed @justinwb have you some recommendation ?
