Issue: Error after Installation

Setup: RAK2287 | WisLink LPWAN Concentrator on RAK2287/RAK5146 Pi HAT in a Raspberry Pi 4

Server: n/a

Details:
No matter if I configure the system as described in the RAK2287 Quick Start Guide with the latest RAK2287 Firmware or if I follow the installation Guide Helium Data Only Hotspot Setup with RAK Concentrator + Raspberry Pi it will result in an Error.
