Hi there,

Don’t run your applications directly on ports 80 and 443, use a web server, I recommend Nginx! Run your apps on random ports and then setup Nginx to listen on 80 and 443, and configure it to route the traffic to your applications. You can find very good tutorials on how to setup and configure Nginx on your droplet in the community!

Good luck!

for meteoar app you need to run

meteor npm install --save bcrypt 

first
than

sudo meteor --port 80

or any port you need
