Could not create ssl tls secure channel works as exe but not in asp net mvc

Introduction

ASP.NET is a popular programming language used for developing web applications. It provides a framework for building dynamic websites, web , and web applications. However, developers often encounter various challenges while with ASP.NET. One common issue is the “Could not create SSL/TLS secure channel” error, which occurs when an application is unable to establish a secure connection with a server.

Understanding the Error

The “Could not create SSL/TLS secure channel” error typically occurs when an ASP.NET MVC application is unable to establish a secure connection using the SSL/TLS protocol. This error can be caused by factors, including incorrect SSL/TLS configuration, outdated SSL/TLS protocols, or issues with the server's SSL certificate.

Resolving the Error

To resolve the “Could not create SSL/TLS secure channel” error in ASP.NET MVC, you can follow these steps:

Step 1: SSL/TLS Configuration

First, ensure that the SSL/TLS configuration in your ASP.NET MVC application is correct. Verify that the correct protocols and cipher suites are . You can do this by checking the web.config file of your application.



  
  
  

Step 2: Update SSL/TLS Protocols

If your ASP.NET MVC application is using outdated SSL/TLS protocols, it may result in the “Could not create SSL/TLS secure channel” error. To fix this, update the SSL/TLS protocols to the latest versions supported by your server. You can do this by modifying the registry settings on your server.

Step 3: Verify Server's SSL Certificate

Another possible cause of the error is an issue with the server's SSL certificate. Ensure that the server's SSL certificate is valid and trusted. You can check the certificate by accessing the website using a web and examining the certificate details.

Step 4: Handle Certificate Validation

If the server's SSL certificate is self-signed or not trusted by default, you may need to handle certificate validation in your ASP.NET MVC application. You can do this by implementing a custom certificate validation callback.


ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, , sslPolicyErrors) =>
{
    // Perform custom certificate validation logic here
    return true; // Return true to accept the certificate
};

Step 5: Check Proxy Settings

If your ASP.NET MVC application is behind a proxy server, ensure that the proxy settings are correctly configured. Improper proxy settings can interfere with the SSL/TLS handshake process and result in the error. Verify the proxy settings in your application's configuration.

Conclusion

The “Could not create SSL/TLS secure channel” error in ASP.NET MVC can be resolved by the steps mentioned above. By checking the SSL/TLS configuration, updating protocols, verifying the server's SSL certificate, handling certificate validation, and checking proxy settings, you can overcome this error and establish a secure connection with remote servers in your ASP.NET MVC application.
