C#: The request was aborted: Could not create SSL/TLS secure channel
Last month we noticed that crawler on which I worked earlier was unable to crawl some of the HTTPS websites. Crawler was built in C# and deployed on several environments running Windows Server 2012 R2. Crawler was running fine on all environments except one where it was unable to connect with few HTTPS websites and it kept raising below exception
The request was aborted: Could not create SSL/TLS secure channel.
Here in this blog post, I will explain how I troubleshot to identify root cause of this exception and its possible solution.
