V2ray-core: 经常failed to process outbound traffic，偶尔能用

Created on 27 Feb 2019 · 8Comments · Source: v2ray/v2ray-core

1) 你正在使用哪个版本的 V2Ray？（如果服务器和客户端使用了不同版本，请注明）
4.15.0

2) 你的使用场景是什么？比如使用 Chrome 通过 Socks/VMess 代理观看 YouTube 视频。
Chrome 通过 VMess链接nginx反向代理

3) 你看到的不正常的现象是什么？（请描述具体现象，比如访问超时，TLS 证书错误等）
偶尔能打开，大多数时候不能打开，过一段时间又恢复工作

4) 你期待看到的正确表现是怎样的？
同样的配置在家里或手机上基本没问题，在办公网络是双网卡配置了默认路由经常出现无法打开的情况

5) 请附上你的配置（提交 Issue 前请隐藏服务器端IP地址）。

服务器端配置:

{
  "log" : {
    "access": "/var/log/v2ray/access.log",
    "error": "/var/log/v2ray/error.log",
    "loglevel": "warning"
  },

          "security": "none"
        }
      ]
    },
    "streamSettings": {
      "network": "ws",
      "security": "auto",
      "wsSettings": {
        "path": "/path/"
      }
    }
  },
  "outbound": {
    "protocol": "freedom",
    "settings": {}
  }
}

客户端配置:

  "log" : {
    "access": "D:\\Program Files\\V2Ray\\access.log",
    "error": "D:\\Program Files\\V2Ray\\error.log",
    "loglevel": "warning"

      }
    },
    {

            "users": [
              {
                "id": "",
                "security":"auto",
                "alterId": 64
              }
            ]
          }
        ]
      },
      "streamSettings": {
        "network": "ws",
        "security": "tls",
        "wsSettings": {

          "geoip:private"
        ],
        "outboundTag": "direct"
      }
    ]
  }
}

Nginx:

    server {
        listen 443 ssl;
        ssl on;
        ssl_certificate       /etc/v2ray/v2ray.crt;
        ssl_certificate_key   /etc/v2ray/v2ray.key;
        ssl_protocols         TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers           HIGH:!aNULL:!MD5;
        server_name server;
        index index.html index.htm;
        root  /home/wwwroot/sCalc;
        error_page 400 = /400.html;
        location /path/ {
                proxy_redirect off;
                proxy_pass http://127.0.0.1:30351;
                proxy_http_version 1.1;
                proxy_set_header Host "server";
                proxy_set_header Connection "Upgrade";
                proxy_set_header Upgrade "WebSocket";
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_intercept_errors on;
        }
    }
    server {
        listen 80;
        server_name server;
        return 301 https://server$request_uri;
    }

6) 请附上出错时软件输出的错误日志。在 Linux 中，日志通常在 /var/log/v2ray/error.log 文件中。

服务器端错误日志:

无错误，没有对应的access记录

客户端错误日志:

7) 请附上访问日志。在 Linux 中，日志通常在 /var/log/v2ray/access.log 文件中。
服务器端没有对应ip访问记录

8) 其它相关的配置文件（如 Nginx）和相关日志。
Nginx没有对应ip访问记录
