Sonarr can only view but Radarr can read and write to Unraid from Proxmox VM

a couple of days ago I head to reboot my Proxmox Sonarr/Radarr VM and I started to experience this problem, that Radarr is able to see and read to a Unraid share with no issues but for some reason Sonarr is not able to.

I use the same mouthing point for both applications,  and within each application I then point to sperate folder.

the mouinting command is 

//UNRAIDIPADDRESS/media /home/istc4/LMDS/media cifs username=USERNAME,password=PASSWORD.rw.user 0 0

when I go to /home/istc4/LMDS/media  I am able to browse with no issues.

as my two applications are dockers I use portainer. I have check the path for each and both are OK, but I can't work out why one can read and write was the other can't

I have point Sonarr to a non Unraid share and it works with no issues, so I know it is a permission problem.

I have attached a copy of the log files from Sonarr in the hope that someone can help

I have gone through and remove any downloaded files names and replace it with DOWNLOAD FILE

/torrents/completed  -- is a local storage to the VM

/TV   -- is the point to  /home/istc4/LMDS/media/tvshows

if it is a Portainer / Sonarr and there is something within the application that I am missing then please point me on the right location, so that I can do some reading up on it and resolve this issue.

many thanks
