Current Behavior

Hello,

I’m working with an OPC UA client and I’m looking for clarification about reconnection behavior.

When the client temporarily loses the connection to the server (e.g., network interruption or server restart), is there any supported or recommended mechanism in the SDK to reconnect the session automatically without recreating existing subscriptions.
I need a new session without old subscriptions

Thank you for your guidance.

@TaheJdidi The SDK has a ReconnectHandler that fulfills this usecase. It also transfers subscriptions to a new Session using the TransferSubscriptionService Set

Thank you for the explanation.

In my case, I explicitly need a new session without reusing or transferring any existing subscriptions.

Is the recommended approach:

to use SessionReconnectHandler and explicitly delete transferred subscriptions after reconnection,

or to avoid ReconnectHandler and create a fresh session manually?

I want to ensure this aligns with SDK and OPC UA best practices.
