Hi, sorry for my previous message, I wanted to preview the message but I pressed the send button. Anyway, if I remember correctly when I tried to browse with version 2022.2 an exception occurred. This exception was not present in the same situation using dlls 2023.1.

Best regards.

Yes i reported in my previous reply:

" Hello, I've tested the connection with OpcUANetDemo with 2022.2 and 2023.1 dlls. The connect exception remains with all dlls versions but with 2023.1 the server is browsable."

Ok, but the browsing is not working with version 2022.2.
Best regards.

Hello, I've tested the connection with OpcUANetDemo with 2022.2 and 2023.1 dlls. The connect exception remains with all dlls versions but with 2023.1 the server is browsable. Now i rebuild my app with 2023.1 and we'll see.
Thank you.

Hello, I have a strange error while connecting to a MEP metal saw. We have problems connecting this machine so i have used the OpcUaNetDemo and tried to play with connection settings. I have tried a connection with UAExpert and I have an error of type 'BadSecurityModelInsufficent'. Clicking on Ignore the machine connects.
QuickOPC version 2022.2.
