Pihole does not start when Host Path chosen for config files

Trying to run Pihole. Once installed with default paths for Config and Dnsmasq (ixVolume) everything runs without problems. As soon as I define custom Host Path for Config and Dnsmasq the app hangs ‘Deploying’. Versions: Truenas Scale 23.10.2, Pihole 2024.03.2. The log:

2024-05-04 09:38:27 Startup probe failed: Get “http://192.168.1.30:20720/admin/login.php”: dial tcp 192.168.1.30:20720: connect: connection refused
