Trouble Accessing Media Files through Serviio - Need Assista

I've been using Serviio for a while now. I'm facing is that I can't access my media files through Serviio anymore. I've followed all the usual steps: setting up the media library, making sure the devices are connected to the same network, and even restarting both the server https://nexus-iceland.wiki/ Work schedule Application, Digital pay slips portal, human Resource Recruitment services and the devices. But no matter what I do, I can't seem to get it to work. Any help or suggestions would be greatly appreciated.
