Hi everyone

Struggling to solve some problems and hoping someone can help, running NC13 on a raspi 3B+ very nooby with this sort of thing.

Is anyone able to tell me if it is possible to plug a usb storage device into my rpi and make the contents available on nextcloud?

I’m hoping to plug my music HDD in to use with Cloudbeats. Is this possible and if it is will a rpi 3B+ handle this for 1-2 users?

Finally, accessing the web UI remotely/outside the network where the device is setup I’m using a free DNS subdomain and I can’t seem to be able to access the WebUI or any of that sort of backend.

Is this possible? Where am I going wrong with this?

Thanks and apologies if I’m doing this wrong.
