How to fix RTMP_Connect0, failed to connect socket. 111 (Connection refused)? - nginx

Question

I'm getting this error when trying to push m3u8 stream source to my Nginx RTMP server
this my FFmpeg command
ffmpeg -re -i https://xxxxxxxxxxxxxxx.akamaihd.net/hls/live/621275/1539097700001/master_1080p.m3u8 -c:v copy -c:a aac -ar 44100 -ab 128k -ac 2 -strict -2 -flags +global_header -bsf:a aac_adtstoasc -bufsize 700k -f flv rtmp://xx.xxx.xx.156/tmp/hls/stream
and this is my Nginx conf file:
#user nobody;
worker_processes 1;
error_log logs/rtmp_error.log debug;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
server {
listen 80;
server_name localhost;
location /hls {
# Serve HLS fragments
# CORS setup
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Expose-Headers' 'Content-Length';
# allow CORS preflight requests
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
types {
application/vnd.apple.mpegurl m3u8;
video/mp2t ts;
}
root /tmp;
add_header Cache-Control no-cache;
}
}
}
rtmp {
server {
listen 1935;
chunk_size 8192;
application hls {
live on;
meta copy;
hls on;
hls_path /tmp/hls/stream;
}
}
}
I assume this is a clear indicator of my problem.
If anyone knows, feel free to comment of course.

Answer 1

your firewall's 1935 port is not open.
open port by:
firewall-cmd --permanent --add-service=http # permanently enable HTTP connections on port 80
firewall-cmd --zone=public --add-port=1935/tcp --permanent
firewall-cmd --list-ports # check
firewall-cmd --reload
for the whole flow of building ffmpeg in Centos, see my tutorial at https://github.com/magictomagic/magictomagic.github.io/blob/master/_posts/2020-05-04-CentOS-FFmpeg-%E6%B5%81%E5%AA%92%E4%BD%93%E6%92%AD%E6%94%BE.md
the environment is CentOS 8.
