setOption httpProxy

client.setOption("httpProxy", proxy);

Not replace old proxy.

Active connections can't have their proxy changed, you need to reconnect.

I only call this function when the connection is unsuccessful, in which case this connection is still considered active?

In short, I set a proxy, get an error: ECONNREFUSED, catch it through on error, replace the proxy and call .logOn again.
