Hi patrol90,

Indeed the issue is quite tricky.
From the log snippets you attached there is no evidence, in the first case, of connections from you adapters.
Maybe, the adapters were launched before the Lightstreamer server, or in any case they tried the connections before the Lightstreamer server was yet listening on the involved ports?
But this also means that the adapters never retried the connection after the first failure.

Regards,
Giuseppe
