Can not access my TRUENAS shared SMB

Hi,
I'm a new user, I tried to connect to my network NAS but it doesn't work at all. SMB scan does not even bring up the server in the list, if I try to add it manually, I get add failed. I can connect to the server with any other device, but not with DMP-A6. I created a Windows shared folder for testing, I managed to connect to it, but I don't have a Windows server and I never will.
Can anyone tell me what SMB protocol do I need to setup on my server? SMBv3 supported by the box?
Is there anyone who successfully connected DMP-A6 to openmediavault or truenas server?
Thanks!

 

I can access the OMV without any problem

 

Thanks! Strange. Which OMV if I may ask, 5 or 6?

 

OMV 6 with latest patch
Default SMb setting

 

I would suggest you create an user profile specific for DMP-A6 and then grant the access to your music folder and this is what I did when I got the failed to add message

 

I will try it

 

No luck.

 

Solved!
Netbios disabled but required so on OMV and TrueNAS you have to reenable that.

On OMV:
omv-env set -- OMV_SAMBA_NMBD_ENABLE "yes"
monit restart omv-engined
omv-salt stage run prepare
omv-salt stage run deploy
systemctl unmask nmbd.service
systemctl stop nmbd.service
systemctl start nmbd.service

On TrueNAS:
menu Network - Global Configuration - enable Netbios

 

OpenMediaVault has now a switch to enable NetBios in SMB settings, but Zidoo team should find a way to make the players work with WSD instead.
