ruby - 视口(viewport)未在 Ubuntu Server VM 中连接

Question

我正在迁移一个通过 EWS 实现用户身份验证的 Redmine 插件。该插件在 Ubuntu 桌面 VM 上运行的 Redmine v4.x 上进行了测试，并且工作正常(可以判断给定的凭据是否有效)。
该插件的主要部分是:

require 'viewpoint'
include Viewpoint::EWS

defaultServer      = 'https://company.mail.server/ews/exchange.asmx'
defaultEmailDomain = '@domain.com'

emailAddress = "username" + defaultEmailDomain
password     = "password"

client = Viewpoint::EWSClient.new(defaultServer, emailAddress, password)
result = client

begin
    client.folders
rescue
    result = 'nope'
end

puts result

此代码适用于以前的 VM 和我的 Windows 机器，但在我的新 Ubuntu Server 22.04 VM 上返回“不”。
我还尝试使用可在新 VM 上运行的 exchangelib 在 Python 中编写一个版本。 IMO 表明该问题与 Ubuntu Server 可能具有的任何网络限制无关。
有什么建议么？
更新:
按照理查德的建议，我保存了救援捕获的错误消息。将错误类型更改为 EwsError 后，我得到以下信息:

附加信息:成功运行用户身份验证的 Windows 测试机器具有与上述相同的 gem 版本。唯一的区别是 Ruby 本身的版本(Ubuntu 上为 3.0.2p107，Windows 上为 3.1.2p20)。
更新:
根据this diff修改openssl.cnf后启用加载旧提供程序，该插件现在可以工作。

尝试调查错误消息。

begin
    client.folders
rescue StandardError => err
    puts err
    result = 'nope'
end
