I got license error when i tried to sign in engine manger page, then I looked into my Wowza server(AWS EC2 instance). Found that 80 port down, and could not reach to license server error from log. And port 1935, 443, 554 also down. I tried to restart WowzaStreamingEngine service, but it could not bring those ports up.
Anyone any ideas?

Hello,
Please check that you have selected or created a security group that has the Firewall Rules for the EC2 instance you are using.
You can get more details about how to do this in the [EC2 User Guide](https://www.wowza.com/resources/WowzaStreamingEngineforEC2_UsersGuide.pdf) on page 13.
Regards,
Alex C.

Hi Alex,
Thanks for your answer.
On AWS EC2 side, yes, I created a security group and allow those ports.
Actually, I looked into Wowza server then found there are no those ports. I used NETSTAT command, please kindly find the result below. Wowza service is running. In this case, how to bring them up? I also tried stop/start wowza service, it doesn’t work.
```auto
- netstat's result:
$ netstat -tlnp
(No info could be read for "-p": geteuid()=500 but you should be root.)
