SFTP Option does not work in the extension but works with the same settings in FileZilla

[Montego02]

I am struggling with this for days now so any help is really appreaciated!

whit this settings:
{
"name": "spaceTCG",
"host": "wpxxx.server-he.de",
"protocol": "sftp",
"username": "ftp12484825",
"password": "xxx",
"port": 22,
"remotePath": "/www/appxxx/v100",
"uploadOnSave": true,
"useTempFile": false,
"openSsh": false
}

I do get acces in Filezilla but with the SFTP Extension I get:
Error: Permission denied
