Hi Carl,

Ideally, yes, or asking on the Paho mailing list.

In this case I can tell you the problem is occurring because you have
the same client ID for your second and fourth clients, so when one
connects, the previous one will be disconnected. Client IDs must be
unique on the broker. Try "scoreboard1", "scoreboard2" and it should
be fine.

Regards,

Roger
