That is, `connect(..., 5000)` threw `ConnectionException` in less than 1s, which is less than both the timeout I provide (i.e., 5s) and the OS defaults to. Am I missing something?

On windows I see you do not get a timeout, but a "connection refused". Also in the log you shared you seem to be using `new Socket(host,port)` so the timeout is the default platform timeout - for which you always get the  `ConnectException`
