In my project, I need to communicate with a Webservice and send data to it. However when I do the envelopment and sent, it shows the following error:

"Could not create SSL/TLS Secure Channel.".

Follows code:

  • You are using digital certificate?

  • Yes, and I’ve used up the Webservice methods, but I can’t access the XML upload. And from what I’ve been informing myself, it doesn’t require authentication, SSL or TLS.

  • Usually this error occurs because there are problems in xml. see if tjce has an xml validation service...

  • I believe that is why, because XML is validated

Germano, try to enter the code below before sending the request, right after the envelopment:

 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

I hope I helped, good luck.

  • Works for me, tanks!!!!

Use the following line BEFORE CREATING THE REQUEST:

ServicePointManager.ServerCertificateValidationCallback = (sender, cert, chain, sslPolicyErrors) => true;

After that the SSL/TLS service will be identified as safe and you can proceed with the request, then your code would look like this:

string xml = @"<tjce:solicitacaoSelo xmlns:ds=""http://www.w3.org/2000/09/xmldsig#"" xmlns:tjce=""http://www.tjce.jus.br/selodigital/schemas"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xsi:schemaLocation=""http://www.tjce.jus.br/selodigital/schemas xsSolicitacaoSelo_v1.0.xsd "">" +
