There is no evidence of a connectivity problem.
The rebind at 23:30:54 demonstrates that keepalive data have been sent normally.
Hence, the issues may be on the Data Adapter side.

Please set the "LightstreamerLogger.subscriptions" logging category at DEBUG level.
It traces both subscription/unsubscription requests to the Data Adapter and updates received from the Data Adapter.

By the way, note that you should not expect unsubscriptions/subscriptions towards the Data Adapter upon a browser page refresh;
in fact, the subscriptions are kept for a few seconds after the old page closes just to ensure that they are still active when the new page starts.
