Precondition:

1. Configure a multinode setup like described here
2. Passive and Gateway node are up and running, Gateway has connected to Passive Node, DLT logs of Passive Node can be received at client connected to GatewayNode

Action:

• Reset Gateway Node without proper shutdown (i. e. do not stop dlt-daemon)

Expected behaviour:

• Gateway Node recognizes unavailability of Passive node and starts reconnecting

Observed behavior:

• Gateway Node does not recognize unavailability of Passive node and no reconnection attempt is started

Traces with Verbose=1 and LoggingLevel=7 are attached: dlt-log.zip
