I think I am having some sort of permissions issues and I am not sure.

Just created my first droplet ever and the steps below are what I have done so far.

Configured SSH Keypair/Access
Created user and added to sudoers
Disabled root logins
Configured firewall to allow http, https, and ssh access
Installed LEMP stack
(Tried to configure Lets Encrypt, but failed. That is another problem for later)

The LEMP stack is functioning correctly and I have access to everything, but when I connect via SFTP using WinSCP I am unable to delete the default index.html file for nginx. Nor am I able to upload any new documents. (I am not using root, I am using the new profile I created and added to sudoers)

I think this may be a permissions issues, but I am not sure?

Thanks :D
