Electron update not completing update with NSIS

[kevinkyle4]

electron-builder version: ^24.9.1
node version: v19.9.0
electron version: ^28.2.0
electron-updater version: ^6.2.1

Have followed tutorial shown in electronjs.org for creating electron update server (https://github.com/ArekSredzki/electron-release-server) and have copied their example for configuring NGINX for the proxy as shown here https://github.com/ArekSredzki/electron-release-server/blob/master/docs/deploy.md

When I configure NGINX I am able to hit the release server and the new electron version is found, then it should it's downloading but the app does not complete. It works just fine without using NGINX. Getting the below error, has anyone been able to configure an update server for electron without using Github or can you shed advice on how to get download to actual complete as I have been unable to locate any meaningful error messages:
