Hey there,

I'm trying to install Technitium DNS in a Docker Container on a Raspberry Pi Model B but I'm getting this error:

Thanks for the post and error log details. The error is being generated when the DNS server starts and is trying to load the config.

It seems that your auth.config file is corrupt which is causing this issue. You need to stop the DNS server and delete the auth.config file and start the DNS server back. The DNS server will auto generate a default file and you will need to configure your users and passwords again. You should find that file in /etc/dns/ folder.

That worked, thanks!
