这看起来和我在 https 中回答的问题完全一样://***.com/a/29611892/3081018.同样的问题:服务器只能做 TLS 1.0 并且只支持 DES-CBC3-SHA 作为密码.在最近的 ruby​​ 版本中，默认情况下不再启用此密码.要连接此密码，请尝试在您的代码中明确指定密码:

This looks like exactly the same problem I've answered in https://***.com/a/29611892/3081018. Same problem: the server can only do TLS 1.0 and only supports DES-CBC3-SHA as cipher. This cipher is no longer enabled by default in recent ruby versions. To connect with this cipher try to specify the cipher explicitly in your code:

http.ssl_version = :TLSv1
http.ciphers = ['DES-CBC3-SHA']
