Dear Support:
After shutting down and restarting the machine, EasyUAClient client cannot reconnect
1) Windows Server 2025 -Version 24H2 (OS Build 26100.1742), .NET8.0 , QuickOPC 5.83.1043.1 (OpcLabs.EasyOpcUA.dll)
2) 2023-03-02 16:53 report: Event Id: 4051 , "OPC_Srv_ConditionChanged.log" batch disconnect log ;
3) EasyUAClient parameter:
easyUAClient = new EasyUAClient() {};
easyUAClient.IsolatedParameters.SessionParameters.HoldPeriod = 15000;
easyUAClient.IsolatedParameters.SessionParameters.RetrialDelay = 60000;
EasyUAClient.AdaptableParameters.SessionParameters.HoldPeriod = 15000;
EasyUAClient.AdaptableParameters.SessionParameters.RetrialDelay = 60000;
EasyUAClient.SharedParameters.EngineParameters.RetrialDelay = 60000;
4)This issue has been receiving feedback all along and is an old problem，Based on our previous feedback, we have updated the driver to the latest version as per your request
5) target IP :10.10.100.114 cannot reconnect; The client is running normally and collecting data normally
6) Why does the target IP always appear as'Disconnected ,opc.tcp://10.10.100.114:4840' in OPC_Srv-ConditionChanged. log'
7) Why didn't you try reconnecting? Two log documents are attached
The above situation has been troubling my project, looking forward to your reply
