I’ve solved the thread.
The timeout was because this system is on an isolated network.
The isolated network IP is 192.168.1.1, but the wifi lan is set to 192.168.1.207 (which gives the device internet for upgraded/updating).
To enable the installation to operate, I changed the IP address to 192.168.1.207 as the DB settings were already set.
This ipaddress was used to generate the default.ipxe file which was what was causing the problem and I over looked it.
