Deployment via SFTP Permission denied

hey guys,

i connected phpstorm with my ftp server via sftp, successfully.

My root path is: "/var/www/virtual/test/htdocs/".

But when i try to change anything and upload this on my server, i get an error:

[23.08.2017 14:40] Automatic upload failed: could not change to work directory "/var/www/virtual/test/htdocs/". (Permission denied)

can anyone help me? thanks :)
