I've developed an ISAPI application that posts xml-questions and receives xml-answers
making use of TElHttpsClient.
Every now and then an exchange fails with error 75778.
However, most of the time, everyting works fine.

I've already contacted "the other side", but they haven't provided me with a possible
reason for this to happen. Maybe you have an idea what the error 75778 means?

My side: Delphi / Secure Blackbox VCL / Client/Server

The other side, gives these headers (when communication succeeds)
Server: Apache-Coyote/1.1
X-Powered-By: Servlet 2.4; JBoss-4.0.4.GA (build: CVSTag=JBoss_4_0_4_GA date=200605151000)/Tomcat-5.5

I do not think this is an bug or error of SecureBlackBox, but I'm still
trying to find the cause of this. I hope you can help.

With regards,

Peet Terluin

When exactly does the error happen? Is it during handshake or during transfer?

Java has certain bugs in SSL/TLS implementation and this can be the reason. We will try to check interoperability with it after 6.0 release, but this takes time.

Please check what version of SSL/TLS protocol is used when the error happens (use Version property to find out). This will let us pay special attention to this version during testing.

Sincerely yours

The error occurs, I think, during handshake.
"OnReceivingHeaders" is not executed and "Active" is false after the exception.

HTTPVersion := hvHTTP11;
Versions := [sbTLS1];

Active will be false in any case if the error happened.
Thank you for version information, this will help us reproduce the issue. I've added a todo item to the list.

Sincerely yours

Oh yes sorry. I thought its a BlackBox Code. The server was ok, but i had to restart the phone..

So its working partially now ;)

Open gets the right cert (i can see in OnCertificateValidate its the
correct CN now).

But the Open ends in this exception?

{SBSimpleSSL.EElSimpleSSLClientError: Connection failed (error code is 75778)
at SBSimpleSSL.TElCustomSimpleSSLClient.Open()
at De.Mms.Dbmm.Wp8.PhoneApp.Services.CertValidationService.SslConnect()}

Could you please check if the desktop application I sent to you works as expected (i.e. if it's a purely WP8 issue)?
