Hello,
i am using SecureBlackbox 13.0.278 as VCL Source in Delphi XE2.

i am using a custom HttpsClient with a Certificate based authentication to send a XML File to specific servers.

one customer can't connect to the servers anymore with his new Certificate. I can reproduce his problem at my computer. The Certificate seems to be OK. I can load the Certificate and the private key into the storage and i can also use it to encrypt data without errors.

i use the following events

Code
    OnData := HttpsClientData;
    OnDocumentBegin := HttpsClientDocumentBegin;
    OnDocumentEnd := HttpsClientDocumentEnd;
    OnReceivingHeaders := HttpsClientReceivingHeaders;
    OnPreparedHeaders := HttpsClientPreparedHeaders;
    OnRedirection := HttpsClientRedirection;
    OnCloseConnection := HttpsClientCloseConnection;
    OnCertificateValidate := HttpsClientCertificateValidate;
    OnCertificateNeededEx := HttpsClientOnCertificateNeededEx;
    OnError := HttpsClientError;



i try to give the information you requested in the other 100354 topics. I tested the connection with the customer certificate for the 2 common servers. At one server i get a wireshark notification. The other one just ends the connection. These are the events:
Code
//Server1:
OnPreparedHeaders
OnCertificateValidate
OnCertificateValidate
OnError : ERROR Nr.:75793 ,Fatal Error ,Remote Error
//wireshark
23   0.317168   IPSource   IPDestination   TLSv1.2   61   Alert (Level: Fatal, Description: Decrypt Error)   54131

//Server2:
OnPreparedHeaders
OnCertificateValidate
OnCertificateValidate
OnCertificateValidate
OnCertificateValidate


Do you have an idea how to track/solve the Problem?
