My loraserver & lora-app-server cannot find the config file

Hi all, I am totally new to this and grateful for all the reply or help I can get here

After I followed the quick start guide here:
I found this interesting situation where I can access the web-interface but somehow the log shows no configuration file found on my system, yet I did follow the setup and even open the file and edit it using
sudo gedit

My question is, why cant it locate the existing loraserver.toml and lora-app-server.toml inside /etc/loraserver & /etc/lora-app-server? How can I fix it?

Again thank you for all kind of help, I have stuck here for weeks and it is giving me a serious headache
