BadCertificateRevocationUnknown - by: Nick

Dear Sir or Madam
we use your QuickOPC 5.23.
When I try to read OPC UA Data with your TestClient "EasyOpcUADemo" everything works. We also used your EasyUaClient integrated in our Testapplication. Now we get the error Message InnerException: OPC-UA service result - BadCertificateRevocationUnknown.
---- SERVICE RESULT ----
StatusCode: {BadCertificateRevocationUnknown} = 0x801B0000 (2149253120)

StatusCode: {BadCertificateRevocationUnknown} = 0x801B0000 (2149253120)
Description: BadCertificateRevocationUnknown
AdditionalInfo: >>> BadCertificateRevocationUnknown

--- at Opc.Ua.CertificateValidator.InternalValidate(X509Certificate2 certificate)
--- at Opc.Ua.CertificateValidator.Validate(X509Certificate2 certificate)

during Read on different OPC UA Servers.

I only get this Error on my Development-PC. On an other Test-PC I can still connect and Read Data with the same Testapplication.
Your Demo Client also still works.

Where can we handle such Certificate issues in the EasyUaClient?

Best Regards
