Hello.

If the exceptions are thrown and then handled internally, which is how I understand your report, they do not affect your program and there is nothing to be concerned about.

Opc.Ua.ServiceResultException: 'BadNotConnected' being thrown during startup was created by CFrayneIonic
Hello,
I'm having an issue where "Exception thrown: 'Opc.Ua.ServiceResultException' in Opc.Ua.Core.dll" is being thrown 4 times while my application is starting up. My application subscribes to multiple nodes on startup then updates a GUI based on the data changes, the 4 exceptions are thrown before the data changes are subscribed to. Having the debug break when the exception is thrown brings me to OPC.UA.Bindings.ChannelAsyncOperation.cs and not where my code is throwing the exception from. Copying the details of the exception gives me this:
Opc.Ua.ServiceResultException
  HResult=0x80131500
  Message=BadNotConnected
  Source=Opc.Ua.Core
  StackTrace:
   at Opc.Ua.Bindings.ChannelAsyncOperation`1.End(Int32 timeout, Boolean throwOnError) in Opc.Ua.Bindings\ChannelAsyncOperation.cs:line 206
My specs are
Visual Studio Version: 17.10.0
.net Framework Installed: net8.0.6
Target Framework: net8.0
NuGet Package: OPCLabs.QuickOpc v5.80.192
OPC version: 2024.1
The program is made on Visual Studio in a Windows Forms App
Thank you,
Connor Frayne
