We are trying to prevent breaking changes, if we can.
But there are situations in which it is not possible.

Ok,
If I remove the lines and replace it with that you suggest it's work fine.
But Why the same code work in the before release and in new release it crash?
For me is not possible that when I update the library I need to review the old code.
Do you agree?

Thanks,
Massimo

Setting an OPC UA certificate acceptance policy specific to an endpoint is not supported, as it cannot be reliably implemented due to limitations of the underlying UA stack. You can set the certificate acceptance policy globally.

To do so, remove the lines
UACertificateAcceptancePolicy uacert = new UACertificateAcceptancePolicy();
uacert.AcceptAnyCertificate = true;
uadesc.CertificateAcceptancePolicy = uacert;
and instead, place the following before the statement with "new easyUAClient()":
EasyUAClient.SharedParameters.EngineParameters.CertificateAcceptancePolicy.AcceptAnyCertificate = true;
Best regards

This below the code:

clientOPCUA = new EasyUAClient();

UAEndpointDescriptor uadesc = new UAEndpointDescriptor();
UACertificateAcceptancePolicy uacert = new UACertificateAcceptancePolicy();
uacert.AcceptAnyCertificate = true;
uadesc.CertificateAcceptancePolicy = uacert;
uadesc.UrlString = "opc.tcp://opcuaserver.com:48010";

UANodeElementCollection uaElColl = clientOPCUA.BrowseObjects(_devModel.UAEndpointDesc,UAObjectIds.Server);

As you can see I'm already going to set the CertificateAccetancePolicy.
where is the mistake?

Hello,

how do you construct your _devModel.UAEndpointDesc? Please post the relevant pieces of code here. Are you setting the CertificateAcceptancePolicy?

I think the error message says quite clearly "Setting an OPC UA certificate acceptance policy specific to an endpoint is not supported, as it cannot be reliably implemented due to limitations of the underlying UA stack. You can set the certificate acceptance policy globally." Isn't that your case?

Best regards
