Dynamic Web Socket URL

I have a flow that connects to Blitortung.org web socket.

There are 10 available web sockets. Is there any way to dynamically set the web socket url incase the web socket fails to connect? I could create all the web sockets but I don't know of dynamically change the socket.

Regards

I found a dynamic web socket node.
