In case of routing issues, the individual socket connections will take ~4.5 minutes depending on OS level socket syn retransmit settings, which means that if there is a connection timeout that is shorter than that, connection will never be established even if other IP's resolve and route properly. This implements concurrent connection attempts with a staggerd delay between attempts. I have chosen not to implement a full version of RFC8305 (Happy Eyeballs) here, as that is a much more invasive change. Signed-off-by: D.S. Ljungmark <[email protected]> Issue: bytebeamio#939
