Permission denied writing files through sftp
I have a droplet running ubuntu 14.04 and a LEMP stack. I have subdomains on the /var/www folder with each having its own folder inside /www. I have one user with root permissions that is the one that I use for ssh and sftp. When I trie to write the file via sftp I have permission denied.
All the folders have 755 and the file have 644.
What do I need to change to get it working?
