Issue with the web socket

We installed traccar in an ip like xx.xx.xx.xx:8082 and using domain for the UI like www.mydomain.com. But when we call websocket from the domain its showing like "Error during WebSocket handshake: Unexpected response code: 503" . Can you please help to solve this issue.

How are you using domain?

In same server we hosted associated application in Apache. And hence the domain name will hit the server. But Apache listens port 80 only.

DNS server resolve ip address of my traccar server.

But domain:8082 is not working

Sounds like you have an Apache proxy. Have you configured websocket proxy as well?

It must look like this.

 ProxyPass /api/socket ws://localhost:8082/api/socket
 ProxyPassReverse /api/socket ws://localhost:8082/api/socket

                ProxyPass / http://localhost:8082/
                ProxyPassReverse / http://localhost:8082/

any sample code pls ,I am a dummy in this scenerio

What code are you talking about?

the proxypass abt apache

You don't need to write any code. You just need to configure it. We have a documentation page for it:

https://www.traccar.org/secure-connection/

I'm sure there's also countless guides online on how to set it up. It's not something Traccar specific.

but aws doesnt it us configure https for elasticip

You need a domain name to have valid HTTPS, but I don't think it's relevant to the question.

Actually I found it relevant because i saw few using aws and it does'nt give https,but as i see web socket needs https. so any way around

WebSocket doesn't need HTTPS. Not sure where you saw it, but it's incorrect assumption.
