Solved Backup Failure with an SshConnectionException

[cruzt]

Trying to figure issues with our current backups. Can anyone shed some light on this?

We are on version 20.0 Update 3 (Build 806).

Your 3CX backup failed due to the following reason(s):
Renci.SshNet.Common.SshConnectionException: Client not connected.
at Renci.SshNet.Session.SendMessage(Message message)
at Renci.SshNet.Sftp.SftpSession.SendRequest(SftpRequest request)

I have the same issue. Would someone be able to help?
My sftp to synology stopped working aswell after the update.

Hello, please try the following:

1) In Admin > Advanced > Parameters add ALWAYS_USE_TMP_FILE_FOR_BACKUP and set to 0.
2) Retry backup and see if it helps.

Adding that parameter resolved the issue!
