After upgrade to 10.2.1, I receive following Notice in the alarm console:

Unexpected Exception [Unable to create connection to MessageBroker. Please see SLMessageBroker.Crash.txt for more information]: Initialize DMA ( at Skyline.DataMiner.Spi.Nats.MessageBrokerConnection..ctor(ISLMessageBrokerFactory messageBrokerFactory)

Looking at the SLMessageBroker.Crash.txt:

2021-12-20 20:10:10.876|SLAnalytics|NATS.Client.NATSNoServersException: Unable to connect to a server.

Both NAS and NATS services are running.

Can you please inform what's the impact of this notice? And how to resolve it? Thanks.
