Braintree 中的“请求被中止：无法创建 SSL/TLS 安全通道”错误

Question

In my local PC Braintree showing error "The request was aborted: Could not create SSL/TLS secure channel" when executing:

 var clientToken = gateway.ClientToken.generate();

I am using "Braintree-2.33.0.dll" and my target .net version is 4.5.1. I have enabled TLS 1.2.

It was working nicely three days ago. But suddenly started showing error. Many people faced same error and most of then have changed the SecurityProtocol . I dont find any way to change that from braintree. Is there any way to change

ServicePointManager.SecurityProtocol

for braintree? or anything else I am missing or need to do? Thanks in advance.

Answer 1

_{Full disclosure: I work at Braintree. If you have any further questions, feel free to contact support .}

You need to update the .NET Braintree SDK you're using to at least version 3.1.0 , the minimum version that supports TLS 1.2. Once compelete, you can validate your setup using the steps here .

On December 13, 2016 , Braintree transitioned sandbox to only accept requests made using TLS 1.2+. After June 30th, 2017, Braintree will no longer officially support any requests in the production environment below TLS 1.2.

Answer 2

Setting this anywhere in your program.cs or startup.cs worked for me, even on versions greater than 3.1:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
