Hello,
we need to obtain some more information.

Can you please instrument your code with storing EasyUAClient log entries into a file, rerun the test, and collect the information?

Hello.

Yes, this is indeed weird. Before further investigation, the first thing to do is to upgrade to the latest QuickOPC version (5.81), rebuild, and retest.

Best regards

Hello

I'm using a service application build with .NET 6.0 and 'm using QuickOPC 5.80.347 version.
This service application monitore and opc item, and then when it changes reads several opc items.
The issue is when I start the opc server and then I run my application all works fine.Then I stop the opc server, the application through the faliure of:
OPC UA service result - {BadSessionClosed}. BadSessionClosed.
OPC-UA client session is not available when connecting the client subscription.
UA SDK error (Opc.UA.ServiceResult=0x80AE0000) in 'static Session.Create'. OPC UA service result - {BadConnectionClosed}. The network connection has been closed.
Then when I start again the opc server I obtain the same error and not reconnect automatically.
This happens when i have the application published out of visual studio but if i run the application in the visual studio en debug or release mode it reconnects so it's what i don't understand, the code is the same for published application or running in the visual studio
