Websocket struggling

Hello!
I’m trying to connect via websocket but I got a status code (503 Service Unavailable) from websocat.
Web bindings are enabled and I can telnet on port 7443 and all stream.management directives are on TRUE.
I see Websocket plugin isn’t compatible with Openfire 4.8.3, what can I do?

Thank you

You do not need a plugin in Openfire 4.8.3 to get websocket support. You can configure them in the admin console under Server > Server Settings > Web Binding.

Once enabled, you will be given the URL endpoints on which websocket connectivity is available. If you cannot connect to those, then the most likely cause is a network issue outside of Openfire.
