My Caddyfile consists of an import directive like import /vhosts/*
I have set up Caddyserver according to these instructions: https://github.com/mholt/caddy/tree/master/dist/init/linux-systemd
and therefore in analogy I have set the owner of the vhosts-directory and its containing files as www-data:www-data and the mod to 444.
When starting caddy I get the following error message:
/etc/caddy/Caddyfile:1 - Parse error: Could not import /etc/caddy/vhosts/flohmarkt-zug.ch: open /etc/caddy/vhosts/flohmarkt-zug.ch: permission denied
What is the proper permission to my vhosts folder and its containing vhost-files?
