Dropping devices

[jiffyjaff]

I'm running the API using the CLI. Its intermittently keeps dropping all devices. The server is always running when this happens (reports OK and 1.2.1 version), but the /device endpoint returns an empty array. The device list will become populated again with all devices intermittently. Any thoughts on what I should check in logs or what might be causing this?

Thanks

Did you find a solution?
For me it seems like all devices is dropped when all devices in our house is sleeping. If a phone wakes up the devices is added again within a few seconds. I've tried pinging the devices and opening the ip:port with telnet to see if I could trigger something, but nothing happens until I unlock my phone.

I also made an issue in the cast-web-api project:
vervallsweg/cast-web-api#155

I couldn’t nail down what was causing it but I think you nailed it. All my devices were asleep just now, but opening the Smartthings app woke them all up. I don’t think this library is being maintained anymore so we’re on our own. I’m going to check the code this weekend to see if we can keep them awake somehow.

I actually don't need to open any app. I think it's because Android phones pulls the status of all Google devices and shows it as notifications.
It also seems like the API disconnects the devices incorrectly for some reason, since they are still awake. So it might be worth looking into why they are disconnected, as this should never be necessary in a normal situation.

The issue looks complex. The problem might be in the project mdns-cast-browser by the same author. In here there's a timeout which seems to trigger the device disconnection: https://github.com/vervallsweg/mdns-cast-browser/blob/master/ttl.js
