我运行的是CouchDB Docker container，V.2.1.1。此时除了SSL之外，其他一切都正常工作。我正在按照CouchDB文档中的SSL设置进行操作。容器具有OpenSSL 1.0.1t。
如文档中所示，我使用的是自签名证书。当我尝试连接到端口6984上的SSL页面时：
Chrome告诉我

"ERR_CONNECTION_CLOSED".

curl 给我

** curl -k https://localhost:6984**

curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to localhost:6984

在服务器日志中，我得到了很多这样的信息。

hello terminated with reason: no function clause matching ssl_cipher:hash_algorithm

搜索最后一个错误会发现Erlang版本有问题。但是，我相信CouchDB容器有一个已经修补过的版本。我确实尝试过升级：

apt-get install Erlang

这没有什么区别。搜索结果还指出OpenSSL的版本有问题。我从源代码升级到OpenSSL 1. 1. 1，重新创建了证书，但问题仍然存在。
按照要求，下面是几个命令的输出。

下面三个命令的输出非常相似。我将只显示不同之处。但是，看起来所有这些命令现在都在进行握手。

{"couchdb":"Welcome","version":"2.1.1","features":["scheduler"],"vendor":{"name":"The Apache Software Foundation"}}

所以我猜LibreSSL的内置版本有问题？下一个问题是可以做些什么？
