Automated backup using iApp does not work after disabling SMB v1 in remote server

Hi,

We were using iApp template / App service to generate UCS backup and copy to a remote server (Windows). Recently we have disabled SMB v1 on the remote server and since then the automated backup does not work.

I have imported the latest iApp template (f5.automated_backup.v3.2.0), but it does not work still.

=====================

====================

Log shows "Permission denied", but I have verified the access on the remote server / share path for the user account in use.

Could someone help on this?
