ZIP gateways sometimes drops S0 encapsulated messages


Sometimes ZIP can’t deliver messages to a device over S0, normally it works fine but in some cases ZIP returns an error saying device is not reachable (few meters from gateway). The issue becomes even worse with some Fibaro Devices, like Fibaro Dimmer 2, where almost every 5-10th message can’t be delivered. Logs give a hint that something wrong with nonce mechanism, but not clear what exactly.

Has anyone experienced the same and how to solve the problem?
