Error during WebSocket handshake: Unexpected response code: 503

[mjdc]

Hello

I try to run a conference demo & after start haproxy and WCS I recive the error

WebSocket connection to 'wss://host_domain:8443/'
failed: Error during WebSocket handshake: Unexpected response code: 503

I run some services on same machine
WCS (wss 8443 ws 8080 8888 ...)
web server ( 443 80 )
haproxy (bind *:8443)

reference - https://flashphoner.com/docs/wcs5/w...up_and_testing-firewall_traversal-haproxy.htm

how to solve the problem?
thanks

It seems you bind ha proxy on the same port as WCS.
WCS is bound on 8443
In your configuration ha proxy is bound on 8443 too.

If you use ha proxy, you can setup ha proxy with single port 443 and setup two mappings:
WCS

1) 443 (webosckets wss) > 8080 (websockets)

Apache or nginx

2) 443 (https) > 80 (http)

Once you have such configuration you will be able to open your pages over https:

https://your-host

and connect to backed WCS server

wss://your-host:443

Thank you for your reply
I tried to change WCS wss port from 8443 to 8433 then it works
Is it mean that WCS only use ws8080 and the wss port can be abandoned or the configs may make some problems?

Maybe your 8443 port was bound by another application.
Try

netstat -nlp | grep 8443

to get more information
