Hello all,
I have a problem with my deployed meteor app. The Start page is not shown, instead it always returns Error 403. The app is deployed on a Debian with the help of nginx + passenger. I have followed this tutorial. Maybe someone has already encountered a similar issue or has an idea 
Thanks for every comment
EDIT: Every information needed will be provided
have you tried accessing it on the running port?
I have no port explicitly configured for Meteor or Node.
My modified config:
server {
listen 443;
server_name my-domain.com;
# Tell Nginx and Passenger where your app's 'public' directory is
root /var/www/app/bundle;
# Turn on Passenger
passenger_enabled on;
# Tell Passenger that your app is a Meteor app
passenger_app_type node;
passenger_startup_file main.js;
# Tell your app where MongoDB is
passenger_env_var MONGO_URL mongodb://localhost:27017/appdb;
# Tell your app what its root URL is
passenger_env_var ROOT_URL https:// my-domain.com;
}
