java.net.ConnectException

tip

Check if your server (or a proxy server) is not going up and down. There might be something between a proxy and a client sending intermittent requests to non-functioning hosts as well. There might as well be too many requests in a short amount of time.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
