![OpenVPN 客户端连接失败(2.5.3)](https://linux22.com/image/768891/OpenVPN%20%E5%AE%A2%E6%88%B7%E7%AB%AF%E8%BF%9E%E6%8E%A5%E5%A4%B1%E8%B4%A5%EF%BC%882.5.3%EF%BC%89.png)
我正在运行 OpenVPN 服务器 2.4.11,并且有许多客户端从各地连接,使用客户端版本 2.4.6。现在我尝试连接运行 2.5.3 的客户端,但没有成功。
我遇到了一些密码问题,所以我有这样的服务器:
#;密码 BF-CBC # Blowfish(默认)
#密码 AES-256-CBC
#;密码 AES-128-CBC # AES
#;密码 DES-EDE3-CBC # 三重 DES
2.5.3 客户端如下:
数据密码 AES-256-GCM:AES-128-GCM:AES-256-CBC 数据密码后备
AES-256-CBC
我的 2.4.6 客户端似乎可以正常连接:
; 密码 x
当我提高客户端日志详细程度时,我得到以下信息:
