[BUG] Polling of Tag value gets stoped after Session keep Alive failure error for a device in OPCUA

[Kiruthick-Roxx]

Description
When the OPC UA session encounters a "Keep Alive" failure, subsequent attempts to update tags fail. This issue persists even after the session is reconnected, causing disruptions in data synchronization.

Steps to Reproduce

• Establish an OPC UA session and start updating tags.
• Simulate a "Keep Alive" failure by disrupting the network or server connection (atleast more than a hour).
• Reconnect the session after the failure.
• Attempt to update tags.
• Expected Behavior:
• Tag updates should resume normally after the session is reconnected.

Actual Behavior
Tag updates fail even after the session is reconnected, requiring a complete restart of the server to restore functionality.

• Node.js version: 18.20
• npm version: 10.9.0
