SFTP test: ALL FAILED

Hello,

I'm experiencing an issue when trying to configure SFTP backups from CWP to Infomaniak Swiss Backup.

Environment
CWP Pro (latest updates installed)
Destination: Infomaniak Swiss Backup (SFTP)
Authentication: Username + Password
Port: 22
CWP Test Output
2026-06-22 11:32:57   SFTP
2026-06-22 11:32:57   SFTP
2026-06-22 11:32:58   SFTP test step1 (key): result=[

The error:

Permission denied, please try again.

makes me think the problem is associated with the access permissions on the destination host.

Can you connect from your CWP server to your SFTP (ssh) server from the command prompt and create files, etc ?
