I'm managing small web app, deploying with (always) FTP. My teammate requested me to upload a folder including small teaser website. As usual routine, I opened the Azure Web App Deployment Center FTP dashboard and copied server address and credentials and pasted them into FileZilla(latest version). Login went well and I could see file list and folders. However, when I tried to upload files, remove existing files, all of the writing attempts failed with 550 Access is denied error. What could be the cause of this?
On the other hands, I could remove existing files on KUDU debug console.
