I have an application with port 9901 and hosted in online server.
If i check this application from the same server with http://127.0.0.1:9901/ or http://127.0.0.1:9901/ the application is run correctly.
What could be wrong?
Here is the netstat of my server:
$ netstat -l | grep 9901 tcp6 0 0 [::]:9901 [::]:* LISTEN
