The underlying connection was closed: The connection was closed unexpectedly

[VinitVishwanathan]

I am using NVP / SOAP APIs. I use paypal sandbox. The Url which I use is :https://api-3t.sandbox.paypal.com/nvp The code was working fine but all of a sudden it stopped working. It gives the following error "The underlying connection was closed: The connection was closed unexpectedly.". Is there anything that is changed in paypal or am I doing something wrong. If you need more details please let me know. Any help will be greatly appreciated

@VinitVishwanathan Thanks for reaching out - unfortunately I haven't work on or with this project for years now, so it's quite possible that many things may have changed with PayPal and the project hasn't kept up. It would be worth reviewing their documentation against this implementation before choosing to use this library, as it isn't being actively maintained.
