When an exception occurs, the connection to the server should be reestablished？ #2569

Type of issue

Current Behavior

My Opcua server is currently built using LabView, and during testing, I have found that ServiceResultException type exceptions are often occasionally caught.

The following types of StatusCodes are high-frequency types: BadConnectionClosed, BadResourceUnavailable, BadSecureChannelClosed,BadSessionIdInvalid,BadNotConnected.

Should I re-establish the connection with the server in the above situation?

The following is a log that records the OpcUa client:

2024 -03-28.Opc.Ua.8888.log

Captured Error at 17:20:40.5051 Ua. ServiceResultException: BadConnectionClosed.

Captured Error at 17:33:04.4723 Ua. ServiceResultException: Error establishing a connection: BadNotConnected.

Captured Error at 17:36:00:4999 Ua. ServiceResultException: BadSecureChannelClosed.

Unfortunately, I am unable to obtain the logs recorded by the server. Please help me analyze the above issue.
