Troubleshooting
sonos discover - no route to host
On error Error: write udp4 0.0.0.0:64326->239.255.255.250:1900: sendto: no route to host (Command exited with code 1)
Note that the port number after 0.0.0.0: is ephemeral and will change and the netmask may not match exactly either
The sendto: no route to host should stay consistent
Advise the user that in direct (no Docker sandbox) mode on Mac OS that Settings -> Privacy & Security -> Local Network will need to be enabled for the top-level host parent process of the Gateway
node if running via launchd
Terminal if running the gateway directly in the terminal
Visual Studio Code if running via terminal in VS Code
An alternative option is to use sandbox (docker container) with network access allowed for that sandbox
sonos discover - bind: operation not permitted
On error Error: listen udp4 0.0.0.0:0: bind: operation not permitted
Advise the user that they may be running via a Codex or other sandbox that does not permit network access (this can be replicated by running sonos discover within a Codex CLI session with sandbox enabled and not approving the escalation request)
