我不确定其他电脑会不会报错

[catna]

mac 系统上面也会报同样的错

目标IP是AWS的嘛？如果是，设置一下 max_hop再试试，添加参数 -m 50

NextTrace v1.1.2 2023-02-20T05:07:06Z 88e69f7 Windows Linux amd64 平台 报同样的错误，无效的内存地址....

测试任何ip均报错，添加参数无效

Hi endercatone,

这个问题是没能从我们的pow api成功领取任务，遗憾的是我们的api服务器已经在国内无法正常使用，我们尝试过更换新域名，但是很快再次被封禁，您可以根据wiki中提到的，设置我们官方提供的proxy来正常使用 nexttrace

export NEXTTRACE_HOSTPORT=nexttrace-io-leomoe-api-a0.shop

如果是Windows用户，可以使用NextTrace的GUI客户端例如OpenTrace直接在图形化界面设置Proxy。

Thanks
