Hey @Dann appreciate the response, I think my nginx config is the issue too but not sure what since the logs arnt much help apart from giving a 404.
No worries, I can wait until Sunday…I have been trying to get this working for over 2 weeks now essentially.
I appreciate all the help and you responding, The end goal is to get it working and I am sure its amazing as compared to preseed Kickstart lol
Happy Friday and Thanks 
i just remembered, did you create the ubuntu 22 mirror in foreman where you
point to the ISO… Also did you uncompress the iso following the docs ?
on another note, if you dont need all the features of foreman and just want
to install OSes quickly, you could look into netboot.xyz with a webserver
serving the cloud-init file… you could have this up and running in
minutes 
The ubuntu 22 mirror is created in Foreman but the location of the iso and uncompressed iso is on a repo server.
Location for the mirror on Foreman is as follows- www.repo.example.com/ubuntu/ubuntu_22.04/
Uncompressed iso: www.repo.example.com/ubuntu/ubuntu_22.04/<uncompressed_iso>
ISO location: www.repo.example.com/ubuntu/ubuntu_22.04.iso
I followed this link to uncompressing the iso
I also want to make a note that I tried putting the user data in a static location on the repo server and the build was working eg
ds=nocloud;s=http://repo.example.com/userdata/ ← has both meta-data and user-data
Sadly I have to go through Foreman
