Multi page Vue app combined with Flask and Nginx - can't run in sub path

I'm running a multi page Vue app, linked with Flask, running on a server with Nginx. I can get this working fine. However, I am going to be running multiple Vue apps on the same server.

I've updated the router.js file:

import Vue from 'vue';
import VueRouter from 'vue-router';
Vue.use(VueRouter)
export default new VueRouter({
    mode: 'history',
    base: '/app1/',
});

And also the vue.config.js file:

module.exports = {
  pluginOptions: {
      electronBuilder: {
          builderOptions: {
              publicPath: '/app1/',
          },
      },
  },
};

And this is a snippet of my nginx config file that is copied here: /etc/nginx/sites-enabled/default

server {
        listen 80;
        server_name website.com;
        error_page  405     =200 $uri;
        include /etc/nginx/mime.types;
        location /app1/ {
                root /Website/frontend/dist;
                try_files $uri $uri/ /index.html;
         }
        location /status {
               include proxy_params;
               proxy_pass http://192.168.1.1:8000;
       }

As you can see, I'm trying to just get the first app running - but I'm having issues.

In the current nginx config - I can access website.com/status fine, but I'm getting a 403 forbidden error when I try and access website.com/app1 or website.com/app1/

If I change in my nginx config file, from

location /app1/ 
to
location /

Then the site works fine.

However, that's problematic as when I want to introduce app2, I will need to point to another dist directory.

The error in the Nginx error logs when I don't have a "/" path, shows that Nginx is trying to look under the folder "/usr/share/nginx/html/". Obviously, I can copy all my files from app1 there and the site works. But again, thats not going to work when I need to expand to additional apps.

If anyone is interested, the issue was the vue.config.js file and that Nginx couldn't find the files in the dist folder linked to app1. Adding this information got it working.

module.exports = {
        publicPath: './',
        assetsDir: './',
        outputDir: './dist/app1/',
};
