Hi @Cfosvang, I have seen similar behaviour. The following was my situation:

- COTS devices that routinely send unconfirmed uplinks and periodically (once per 24hrs in my case) send confirmed uplinks. If uplink is not confirmed then device enters an OTAA join process.
- Gateway RX continues normally and forwards the device uplinks to the core.
- Gateway TX has silently failed and downlinks are not TX’d to devices.
- Devices are stuck in OTAA join loop.

In my situation power-cycling the gateway fixed the situation.
