Welcome

Description of the problem

vless-grpc conflicts with fakeip. Replacing fakedns dns server with directdns make it work though.

Version of sing-box

```console $ sing-box version sing-box version unknown Environment: go1.20.2 windows/amd64 Tags: with_quic,with_grpc,with_dhcp,with_wireguard,with_shadowsocksr,with_ech,with_utls,with_reality_server,with_clash_api,with_v2ray_api,with_gvisor CGO: disabled ``` complied with ```powershell go install -v -trimpath -tags "with_quic,with_grpc,with_dhcp,with_wireguard,with_shadowsocksr,with_ech,with_utls,with_reality_server,with_clash_api,with_v2ray_api,with_gvisor" github.com/sagernet/sing-box/cmd/sing-box@dev-next ```

Solved. server needs to be an IP address.

    {
      "tag": "Proxy-gRPC",
      "type": "vless",
      "server": "1.2.3.4", // IP address here
      "server_port": 443,
      "uuid": "uuid",
      "tls": {
        "enabled": true,
        "insecure": false,
        "server_name": "example.com"
      },
      "transport": {
        "type": "grpc",
        "service_name": "servicename"
      }
    }
