Failed to start: app/proxyman/inbound: failed to listen TCP on

[transmirro]

最近出问题后重装，查看status都是运行，但是运行“/usr/local/bin/v2ray run -config /usr/local/etc/v2ray/config.json”后发现
“Failed to start: app/proxyman/inbound: failed to listen TCP on xxxx”。

查了端口没有被占用，也没有被v2ray使用，防火墙也没有占用。

服务器配置如下
{
"inbounds": [
{
"port": xxx,
"listen":"127.0.0.1",
"protocol": "vmess",
"settings": {
"clients": [
{
"id": "uuid",
"alterId": 0
}
]
},
"streamSettings": {
"network": "ws",
"wsSettings": {
"path": "/xxx"
}
}
}
],
"outbounds": [
{
"protocol": "freedom",
"settings": {}
}
]
}

error.log里也没有信息。
这个是哪里配置出问题了吗？
