Bug Description

Hi,
im on v0.41.0.

I have a SFTP Volume, configured via password. When i create a volume and i enter my password and click "Test Connection" and save it, it works. Backups work, no problem.

But when i then go back to the volume settings, the password is then shown as encv1:14aa3..... which is intended and normal. BUT, the "Test Connection" is broken in this state. The encrypted password is "broken", as it fails then like this:

20:25:08 info Executing sshfs: sshfs root@192.168.178.3:/ /tmp/zerobyte-test-jEcNPH -o reconnect,ServerAliveInterval=15,ServerAliveCountMax=3,allow_other,uid=0,gid=0,no_contain_symlinks,UserKnownHostsFile=/tmp/zerobyte-ssh/c73868d2d5551787.known_hosts,StrictHostKeyChecking=yes,port=1907 -o password_stdin

20:25:11 error Error mounting SFTP volume {

  "error": "Failed to mount SFTP volume: read: Connection reset by peer"

}

20:25:11 info SFTP volume at /tmp/zerobyte-test-jEcNPH unmounted successfully.

But during this configuration, when i get rid of this encrpyted password and enter the raw password again, it works:

20:26:17 info Executing sshfs: sshfs root@192.168.178.3:/ /tmp/zerobyte-test-pEddKD -o reconnect,ServerAliveInterval=15,ServerAliveCountMax=3,allow_other,uid=0,gid=0,no_contain_symlinks,UserKnownHostsFile=/tmp/zerobyte-ssh/3cdfb8f77945b933.known_hosts,StrictHostKeyChecking=yes,port=1907 -o password_stdin

20:26:18 info SFTP volume at /tmp/zerobyte-test-pEddKD mounted successfully.

20:26:18 info SFTP volume at /tmp/zerobyte-test-pEddKD unmounted successfully.

But the funny thing is, even tho the password is shown in encrypted format and the "Test Connection" fails, the backup works, if triggerd from Backup Schedule:

20:27:18 info Starting backup Backup "Raspberrypi" for volume raspberrypi to repository nas-repo

20:27:26 info Backup Backup "Raspberrypi" completed successfully for volume raspberrypi to repository nas-repo

20:27:26 info running retention policy (forget) for schedule 11

20:27:47 info Retention policy applied successfully for schedule 11

To sum up:
While the backups work, once the encrypted password is visible in the volume configuration, the "Test Connection" fails.

PS: The "Check now" Function works, its only the "Test Connection" that fails.
