Dear OPC support,
we are encountering below error when fetching tags. Please guide on it.
An OPC-UA operation failure with error ID 'OpcLabs.UAEngine=1' occurred, originating from 'Opc.Ua.Core' and with depth of 2. The inner exception, of type "OpcLabs.EasyOpc.UA.Engine.UAEngineException", contains details about the problem. at OpcLabs.EasyOpc.UA.IEasyUAClientExtension.Read(IEasyUAClient client, UAReadArguments readArguments)

UA SDK error (Opc.UA.ServiceResult=0x801A0000) in 'ApplicationInstance.CheckApplicationInstanceCertificate'. OPC UA service result - {BadCertificateUntrusted}. The certificate is not trusted.
+ The error occurred while creating or checking the (client) application instance certificate. Check event log entries for errors and warnings.
+ Suggestion: Check the trusted peers certificate store for the presence of the application instance certificate. This error can happen if the instance certificate is in the application instance store, but not in the trusted peers certificate store.
+ The certificate generator path was "E:\Scheduled Tasks\Maximo Integration\QCs_PLC - Copy\Opc.Ua.CertificateGenerator.exe".
+ This is an engine-level error. It is unrelated to any specific target server connection.
