I’m new using lora, and I managed to get the things stack open source running on a server, but I got a problem with end devices, after 3 hours or so, the live data stream stops and some of the device’s parameters are missing, specifically Frequency plan, LoRaWAN version, Regional Parameters version, and AppKey, i got no idea what’s going on, after that I need to restart the docker, delete de device and create a new one generating a new DevEUI and AppKey, then change those keys in the code for the heltec board to receive data again. ![Screen Shot 2024-06-27 at 8.10.54 AM copy](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/2/5/251afbff4ebed846f3565c37748af2447345471e.png) ![Screen Shot 2024-07-16 at 10.27.25 AM copy](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/3/6/36be1ee1ee6fe098a1fd4ba754cb7749211e1764.jpeg) I’m using as end device a “heltec lora wifi v3” to send data to a “DLOS8N Outdoor LoRaWAN Gateway” that is connected to a digital ocean’s droplet that’s running the things stack (server is running Debian), for the end device settings in the things stack I’m using OTTA. Any help would be appreciated.
