Problem with mounting off network drive

i have an issue, my main nas is located at office i want volumio to read the music from the nas i have a tunnel created on nas following it’s ip address i tried http service and smb and tcp but nun worked i can’t make my volumio running on RPI 4 read the files

I’ve not attempted to mount a NAS that has an external IP address. I have, however, run into issues trying to mount a NAS that’s on my home network. I eventually found a solution: see towards the end of this thread.
