不確定這是否是最好的問題，但在2017年6月30日的PayPal TLS 1.2升級後，我無法使用他們的沙箱NVP端點：如預期https://api-3t.sandbox.paypal.com/nvpTLS 1.2升級後PayPal沙箱API SSL錯誤errno 54
活API https://api-3t.paypal.com/nvp作品：
~ % curl "https://api-3t.paypal.com/nvp?user=whatever"
ACK=Failure&L_ERRORCODE0=81002&L_SHORTMESSAGE0=Unspecified%20Method&L_LONGMESSAGE0=Method%20Specified%20is%20not%20Supported&L_SEVERITYCODE0=Error
我從服務器獲得響應的身體。
但是，如果我嘗試使用沙箱相同的請求，我得到：
~ % curl "https://api-3t.sandbox.paypal.com/nvp?user=whatever"
curl: (56) OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 54
我試圖迫使TLS 1.2和不安全連接的幾種組合，但他們不會有所作爲。這裏有一個冗長的輸出：
~ % curl --insecure --tlsv1.2 -v "https://api-3t.sandbox.paypal.com/nvp?user=whatever"

我在MacOS和嘗試升級OpenSSL和捲曲的MacPorts與本人取得php70捲曲相同的行爲，這也是最新的使用OpenSSL 1.0.2l。也同後一行爲FreeBSD的機器上使用OpenSSL 1.0.2k快速檢查：
* SSL read: error:00000000:lib(0):func(0):reason(0), errno 54
* Curl_http_done: called premature == 1
* stopped the pause stream!
* Closing connection 0
curl: (56) SSL read: error:00000000:lib(0):func(0):reason(0), errno 54
任何幫助，非常感謝
你可以用openssl s_client -connect api-3t.sandbox.paypal.com:443 -tls1_2 -servername api-3t.sandbox.payp來排除OpenSSL al.com'。 '-tls1'失敗，而'-tls1_2'成功。 cURL還告訴你，問題出現在其他地方，當它報告*「TLS握手，完成」*。 – jww
