Our RAK7289V2 gateway is using WisGateOS 2.1.2 and is connected to AWS IoT Core as NS and to WisDM for monitoring.
Both the AWS and WisDM connections have been working fine when the gateway was connected via ethernet and also a short while when the gateway was connected via LTE and powered with solar panel and the RAK Battery Plus.
After running the gateway with 10 sensors communicating via the gateway for 1 day the gateway went offline. Both in AWS and in WisDM the gateway is seen as offline.
Restarting the gateway made it come online again for a short while before going offline again. During the short online time we could see that the battery was charging and that there was enough power to run the gateway, this we could se using the solar battery extension installed in the gateway as well as in WisDM.
In the gateway we also installed the open VPN extension and even if the gateway is seen as offline in AWS and WisDM the VPN client in the gateway is connected to our OpenVPN server becuase I can both ping the gateway and connect via SSH to it from my computer that is also connected to the same OpenVPN server.
Does anyone have any insights into how this can happen and what it is that has broken the gateway connection to AWS and WisDM?
Also does anyone have any advice for how to find the log files via SSH or how I can reboot the gateway via SSH to try to find out what has happened. I couldn’t find any log files when lookking around in the file system, at leats no log files that actually said anything of value.
