Issue

During boot sequence, NCP is trying to get an IP for a domain. It seems to be asking this to quickly, and is pasting this in the trusted proxies section of the nextcloud config file :

'trusted_proxies' => array (
0 => '10.0.50.10',
1 => '127.0.0.1', 2 => '::1',
11 => '127.0.0.1',
12 => '::1',
14 => ';; communications error to 10.0.50.1#53: host unreachable ;; communications error to 10.0.50.1#53: host unreachable 10.0.50.20', ),

It is fully reachable at some point, and I am able to do a manual "dig".

The quick fix is to find :

local domain_ip="$(dig +short "${host}")"
[[ -z "$domain_ip" ]] || ncc config:system:set trusted_proxies 14 --value="$(dig +short "${host}")"

In /usr/local/etc/library.sh, and replace it with this :

local domain_ip="$(dig +short A "${host}" 2>/dev/null | grep -E '^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$' | head -n1)"
[[ -z "$domain_ip" ]] || ncc config:system:set trusted_proxies 14 --value="$domain_ip"

I will propose a fix to the code myself.
