WantWriteError when syncing > 100 kB files

[raphael0202]

On linux, I get a WantWriteError from the OpenSSL library when I try to upload a file > 100 kB using the sync client:

Hi, how are you running PydioSync? Did you try from another platform? What's your server version and configuration (ssl wise) like? Does it work without SSL?

[raphael0202]

Hello, sorry for my late answer. I'm running PydioSync from directly using python main.py in the src folder, latest version from Github. I only tried on Linux. Using Nginx 1.9.10, SSL certificate obtained from Let's encrypt. And I haven't tried without SSL, as the Pydio server is in production and heavily used, I would rather not.

edit: The Nginx server performs a redirection on the 443 port, I need to modify this setting to be able to connect without SSL.
