Connection never recovered sometimes [Java]

[DarioCrivelli]

I see; the simple recovery mechanism offered by the ls_proxy layer is too simple for this case.
This means that you cannot take advantage of the internal reconnection loop that follows when you set connectionRetryTimeoutMillis to a nonzero value.
By setting connectionRetryTimeoutMillis to 0, your code will receive a onFailedReconnection invocation on the PushErrorListener, with a suitable PushException. Then, by invoking rethrow() on this exception, you will get the original PushUserException with the relevant error code, based on which you should setup the proper recovery action.
Sorry for the hassle.
