I am using Paypal Sandbox account with Soap API Signature Asp.net C#
The same code works for me on live Paypal account, but it does not work in the sandbox.
Paypal sandbox throws error
The request was aborted: Could not create SSL/TLS secure channel
Is there any help please
This usually happens if you try to connect to api.sandbox.paypal.com
without supplying an API certificate. Try using api-3t.sandbox.paypal.com
instead.
Since you did not say what Urls you are using, we can't say right or wrong.
Here are the Urls for PayPal.
