No Reachable Server Error when migrate our parse app using mongodb URI

[komalkk]

I am using mongodb version 3.0.11 on ubuntu server, but when I migrate our existing parse app in aws for production, after installing mongodb on ubuntu server when click on migrate button after changing the mongodb uri with "mongodb://username:password@IP Address:27017/Database name" it shows the error
"No Reachable Server".
I am using below link for migration -
http://julienrenaux.fr/2016/01/29/complete-parse-server-migration-guide/
also please insure me that this link is good for production purpose using mongodb or any other is useful.

please help me for resolving the issue.

check security group, make sure that the ports are open in inbound connections

I'm closing out this issue as it is not related to Parse Server. For migration assistance, please visit https://parse.com/help#report

Thanks, benishak
Yes this issue is related to security group, I had connected the 27017 port to EC2 security group, therefore I am not able to connect it and facing this error - "No Reachable Server".
after connecting the port 27017 to anywhere, I am able to connect and migrate the app.
