Chirpstack on RAK Common Gateway unresponsive after a few days

Hello everyone, I have been running Chirpstack using the RAK Common Gateway on my RAK5146 concentrator module. Unfortunately, I have stumbled upon a problem that has happened repeatedly now where the Chirpstack Application Server is not reachable anymore. Restarting the Raspberry Pi and reconfiguring the concentrator using the gateway-config menu also didnt do anything. Has anyone had the same problem? Its pretty annoying because at the end, I have to create a new image and set up the Chirpstack server all over again losing all my work and my connected end nodes. Any help would be greatly appreciated.
