[asterisk-users] Asterisk websocket with Nginx 502 Gateway error

[Steve Ng]

Hi all,

I am using the following set up:
SIPML5 --> Nginx --> Asterisk, where NGINX as a reverse proxy, main purpose
is to take in wss and route to Asterisk's ws.

However, I am facing this issue recently where Nginx will return 502
gateway error of

8018#0: *24183 upstream prematurely closed connection while reading
response header from upstream, client: 116.15.31.xxx, server:
asteriskstage.xxx.yy, request: "GET / HTTP/1.1", upstream: "
http://127.0.0.1:8088/ws", host: "asteriskstage.xxx.yy"

Anyone has any idea why?

Here's my nginx config:

Regards,

Steve
