HUE: Connection refused

[dannybloe]

I am running Domoticz here on a Pi3 using the Hue plugin. So far so good. It polls every 10s for updates. But… regularly (every 1 or 2 days) it suddenly cannot connect anymore to the bridge (Error: Philips Hue: Error getting Light States, (Check IPAddress/Username)). Using curl on the Pi, the bridge reports a ‘Connection refused’ on the api. If I do the same api request using the same user key on a different machine in the network I do get a proper response. Looks like the bridge does some kind of ip blocking. I have to restart the bridge to make things work again.

What could be causing this? Anybody else seen this behaviour?

Cheers,

Danny
