Have you also installed another web server like Apache? The errors here indicate that ports 80 and 443 are already in use on your droplet by another service.

No, I'm not using Apache.........
Steps whatever i have did...

  1. Node
  2. WebRTC (MCU)
  3. Nginx

My MCU is working ...

[root@localhost Release-v3.4]# ls
audio_agent     bin              extras  NOTICE  package.json  recording_agent  sip_agent   ThirdpartyLicenses.txt  webrtc_agent
avstream_agent  cluster_manager  logs    nuve    portal        session_agent    sip_portal  video_agent
[root@localhost Release-v3.4]#
[root@localhost Release-v3.4]#
[root@localhost Release-v3.4]# cd bin
[root@localhost bin]# ls
daemon.sh  detectOS.sh  epel-release-latest-7.noarch.rpm  init-all.sh  init-mongodb.sh  init-rabbitmq.sh  restart-all.sh  start-all.sh  stop-all.sh
[root@localhost bin]# ./start-all.sh
nuve running as process 19238.
cluster-manager running as process 19320.
portal running as process 19358.
session-agent running as process 19397.
webrtc-agent running as process 19457.
avstream-agent running as process 19517.
sip-agent running as process 19576.
recording-agent running as process 19640.
audio-agent running as process 19700.
video-agent running as process 19762.
sip-portal running as process 19829.
app running as process 19871.
[root@localhost bin]# cat /home/raviranjan/Release-v3.4/logs/woogeen-app.stdout
1 rooms in this service.
MyRoom Id: 5aaa48e9258bfc717b77b808

After that I'm doing to test my Nginx It's also fine but when I am trying to reload my Nginx Server its going to Failed...

I already mention about what is my Error!
