I've made an app using eve, and when I run 'python run.py', I receive 'Running on http://127.0.0.1:8000/', but when I try to access that from my laptop's browser (22.214.171.124:8000), I'm unable to connect.
If your application is binding in localhost (127.0.0.1), you need to access this IP address only by the server where the app is running. Or you have the optional to change the bind to another IP and access remotely.
Other optional is to make a tunnel trough ssh and access remotely like you are localy.
It will depends what library are you using, basically you need to tell on what IP's the application will bind.
Usually is something like the example bellow (if you are using eve), to listen on all IP addresses.
