To troubleshoot the connection hang after migrating your QNAP Roon Server to a Docker container, perform the following steps:
Restart the Container: Open QNAP Container Station and restart the Roon Server container.
Provide YAML Configuration: Share the exact YAML code you used to deploy the container so we can verify the network mode settings.
Toggle Local Network Permissions: On your remote device (iOS or macOS), open the system settings, locate the Roon app, and toggle the "Local Network" permission off and back on.
Provide the YAML code so we can review the configuration and proceed.
