Getting error "The request was aborted. Could not create SSL/TLS secure channel"

fineblumcb — Mon, 23 Jul 2018 21:25:35 GMT

Getting "The request was aborted. Could not create SSL/TLS secure channel" error all of a sudden. What has changed? Was working good before.

I'm using the API to run transactions from a WinForms application.

Thanks.

Hi fineblumcb,

Are you using the .NET SDK? If so, what version. If you are using another SDK language, which one and what version?

Could you also provide more detail about the which call(s) you are attempting to make and to what endpoint?

Lastly, if you run a scan of your server name at https://ssllabs.com/ssltest and provide the complete results, including cipher support, it may be helpful.

Thank you,

Elaine

Hi Elaine.

I'm testing against both the Sandbox and Production servers with same outcome. I reinstalled the libraries so I must be using the latest version of the SDK. The code I'm using is indentical to the "Hello World" example.

I don't have a server so I don't know what to use as the HostName for SSLlabs site. I'm not running it on a web page. It's running from a Windows Desktop application developed in WinForms C#. I take it the SDK uses the .Net WebClient class to contact the endpoint URL.

Thanks.

What version of Windows are you using?

I would also like to confirm that you are using the .NET SDK version 1.9.4 or 1.9.5 just to rule that out as these are the version that support TLS 1.2, which is necessary to connect with our endpoints.

As this error indicates that your server cannot connect to the endpoint you are pointing to, I would assume that this would occur in both Sandbox and Production.

There is a stackoverflow post that discusses this error in C# at:

https://stackoverflow.com/questions/2859790/the-request-was-aborted-could-not-create-ssl-tls-secure-channel#

Please review and address these questions and I will be happy to review this further.

Thank you,

Elaine

Hi Again.

I decided to move the API to my webservice. Working on that now. Simulating an HTTP Post directly from the Desktop to the API endpoint may be the problem. It did work before, but I would not be surprised if it is no longer allowed. This way the API will be running on a webserver with an SSL certificate. My guess is the message is failing the encryption test.

Thanks.
Charlie

Hi, did you get any proper solution, I think I am facing the same issue.

The error message "The request was aborted. Could not create SSL/TLS secure channel" typically occurs when there's an issue establishing a secure connection via SSL/TLS. This can happen for several reasons, and here are some steps you can take to troubleshoot and resolve the issue:

1. **Check SSL/TLS Configuration**: Ensure that the SSL/TLS configuration on the server you're trying to connect to is properly set up and compatible with the client making the request. Sometimes, mismatched or outdated SSL/TLS versions or cipher suites can cause connection issues.

2. **Verify Server Certificate**: Make sure that the server you're connecting to has a valid SSL/TLS certificate issued by a trusted Certificate Authority (CA). If the certificate is expired, self-signed, or not trusted by the client, it can cause SSL/TLS handshake failures.

3. **Check Firewall and Proxy Settings**: If you're behind a firewall or using a proxy server, verify that they are not blocking or interfering with the SSL/TLS connection. Ensure that the necessary ports (e.g., 443 for HTTPS) are open and accessible.

4. **Update SSL/TLS Libraries**: Ensure that the SSL/TLS libraries used by your application or framework are up to date. Older versions of SSL/TLS libraries may lack support for newer encryption algorithms or security protocols, leading to connection failures.

5. **Check System Date and Time**: Ensure that the system date and time on the client machine are correctly set. SSL/TLS connections rely on valid certificate expiration dates, and an incorrect system time can cause certificate validation failures.

6. **Inspect Intermediate Certificates**: If the server is using an intermediate certificate, ensure that it is properly configured and accessible to the client. Missing or misconfigured intermediate certificates can cause SSL/TLS handshake failures.

7. **Enable Detailed Logging**: Enable detailed logging in your application or framework to capture more information about the SSL/TLS handshake process. This can help identify the specific stage at which the connection is failing.

8. **Test with Different Clients**: If possible, test the connection from different client machines or environments to see if the issue is specific to a particular configuration or setup.

9. **Consult Service Provider Documentation**: If you're connecting to a third-party service or API, consult their documentation or support resources for any specific SSL/TLS requirements or known issues.

10. **Contact Service Provider Support**: If you're still unable to resolve the issue, contact the service provider or server administrator for assistance. They may be able to provide further insights or troubleshoot the issue from their end.

By following these steps and investigating the potential causes of the SSL/TLS connection error, you should be able to diagnose and resolve the issue effectively.
