Hello.

I am glad that it works now. Can you share how you made it - what was wrong or needed to change?

Best regards

Hi,
thank you for the screenshots.

The "Server Endpoints" tab is correct, I believe it should work with these settings.
The "Trusted Clients" is not quite correct, your clients should appear there, either as Trusted, or at least Rejected initially. This is of course not the reason for the problem, but rather an effect of the problem (because the communication does not get that far for the server to "see" the client certificates), so nothing to be fixed right there. But it is helpful for me to know!

I now need two additional pieces of information please:

1. When you are trying to connect to the server using some of the applications written with QuickOPC , do you get any client-side popups asking you to confirm the server certificate?

2. Please figure out the full version number (including build/revision - the 4 parts altogether) of QuickOPC you are building with.

Best regards

Hello,
thanks, unfortunately there isn't much detail in this server log.

Can you post here screenshots of the "Server Endpoints" and "Trusted Clients" tabs of the "OPC UA Configuration Manager" of the server?

Regards

Hello.

Regarding the security settings: I would reserve playing with them for later. But here is the info:

What do you mean by "I don't see anything on the server side..."?. Is there something like a server log, and are you saying that it is empty? Or you just do not know where it is or are you saying that the server does not have that?

Regards

There should be something in the server that would tell you why it is giving BadSecurityChecksFailed .
