WebSocket Connection "Got unexpected status 503"

[wmshek1992]

Hi,

I am using Mac. I am testing my websocket server and encountering error in websocket open connection.
I'm sure my server working fine and I can connect my server with the URL I set in the websocket open connection.

When I run the server on local, it has no problem with the test.
But it gives errorr code 503 when I try to test the remote server with wss.
Do you have similar experience?
