Hi all,

I am new to here, and I already install kurento media server using aws template provided by official doc. then I clone the project from remote github, and run application.

```
git clone https://github.com/Kurento/kurento-tutorial-java.git cd kurento-tutorial-java/kurento-hello-world git checkout 6.18.0 mvn -U clean spring-boot:run \ -Dspring-boot.run.jvmArguments="-Dkms.url=ws://{KMS_HOST}:8888/kurento"
```

I replaced {KMW_HOST} with my ec2 public Ip addr, but it does not work. I try to use postman send a websocket request, it still does not work.

```

I guess the EC2 machine has a server firewall (Security Group) that rejects incoming connections from the public internet, for security of the machine.

Check
https://aws.amazon.com/premiumsupport/knowledge-center/connect-http-https-ec2/
and see if opening up the port solves the issue.

You'll need to open the port range of RTP or WebRTC in order to allow incoming connections, or else use a STUN/TURN server to open ports in the NAT:

Thanks for you advice and resources.
I checked security group before, kurento AWS template already open the port which is needed. I agreed with you about using STUN/TRUN service connect kurento server and browser client, but I encounter problems when I established application server. 
But thanks anyway!
