无法连接之异常

机器过期忘记续费停机了一天，但续费后v2ray死活连不上，有如下报错
服务端：

2022/05/27 02:17:28 [Info] [50130167] app/proxyman/inbound: connection ends > proxy/vmess/inbound: invalid request from 58.48.189.174:0 > proxy/vmess/encoding: connection drained DrainSize = 1589 23 2 > proxy/vmess/encoding: invalid user: VMessAEAD is enforced and a non VMessAEAD connection is received. You can still disable this security feature with environment variable v2ray.vmess.aead.forced = false . You will not be able to enable legacy header workaround in the future.

排查了客户端和服务端时间同步问题，再就是配置也没有动，突然就连不上了确实很奇怪。查了下资料按照如下方法解决：

1.执行 systemctl status v2ray 命令
2.若步骤1正常输出v2ray的信息 ,观察Drop-In:后面的路径 ,如: Drop-In: /etc/systemd/system/v2ray.service.d
3.进入上述路径 cd /etc/systemd/system/v2ray.service.d
4.执行 ls 命令看是否有一个 .conf后缀的文件,如 10-donot_touch_single_conf.conf
5.vim 修改这个文件: vim 10-donot_touch_single_conf.conf
6. 在[service]下添加一行信息: Environment="V2RAY_VMESS_AEAD_FORCED=false"
7. 文件修改保存后,再执行 systemctl daemon-reload
8. 执行 systemctl restart v2ray
