Hi,

See the attached document that shows all the steps in UA Expert to connect to the Honeywell OPC UA server.

I understand that supporting us with this issue is out of the scope of your support. Are you willing to remotely connect to the customer's computer (in Belgium) and help us for an additional fee?

I appreciate your answer.

Thank you.

Michael

You will have to show me the UaExpert does that. Maybe it asks the user whether he wants to trust an otherwise unaccepted certificate anyway. Or is not connecting securely (with the use of certificate) at all. There are multiple possibilities.

To the question: "What do you recommend?" : I have already answered that. The CA certificate(s) need to be placed into the Trusted issuers store (in addition to Trusted peers). This is fairly standard procedure.

There are also ways to tell QuickOPC to blindly accept the certificate anyway, but of course that's totally insecure.

Hi,

Thank you for your answer. So if something is wrong with the certificate how come that the UA Expert is able to deal with it and browsing is Okay?

I don't know what kind of certificate is it. Our OPC Client software is installed in the customer's site in Belgium. He needs to connect to the UA Server...

What do you recommend?

Thank you.

Michael

From the name of the issuer of the server certificate ("CN=GTCHVE3SA01 Root CA."), I can guess that this is not a self-signed certificate, but a certificate issued by a certificate authority, i.e. a part of the PKI infrastructure.

In this case also you also need to manage the CA certificates (the trusted CA certificates need to be in Trusted Issuers certificate store). This is more complicated than with self-signed certificates.

You need to get a reasonable understanding of how this kind of security setup works, but explaining it is outside of the scope of the forum and our tech support. There are whole parts of the OPC UA specification dedicated to it. I am willing to help, but mainly with issues that have to do with specifically with QuickOPC support for this.

Hi,

I am getting an exception when trying to connect to an OPC UA Server (Honeywell EBI). See the details below. Browsing is Okay when using UA Expert using the same security policy and security mode.
