not able to connect with API proxypanel
Hi everyone, I have a problem with using **proxypanel**.

I tried with xmrig-proxy_win32bit v.2.4.5 with this configuration:
```
{
    "background": false,
    "log-file": null,
    "access-log-file": null,
    "retries": 5,
    "retry-pause": 5,
    "donate-level": 0,
    "coin": "xmr",
    "custom-diff": 100,
    "syslog": false,
    "verbose": true,
    "colors": true,
    "workers": true,
    "pools": [
        {
            "url": "pool.supportxmr.com:5555",
            "user": "wallet",
            "pass": "PROXY"
        }
    ],
    "bind": [
        "0.0.0.0:8888"
    ],
    "api": {
        "port": 6666,
        "access-token": null,
        "worker-id": null
    }
}
```


I tried with xmrig-proxy_win64bit v.2.5.2 with this configuration:
```
{
    "access-log-file": null,
    "algo": "cryptonight",
    "api": {
        "port": 6666,
        "access-token": "test",
        "worker-id": null,
        "ipv6": true,
        "restricted": false
    },
    "background": false,
    "bind": [
        "0.0.0.0:8888",
        "[::]:8888"
    ],
    "colors": true,
    "custom-diff": 100,
    "donate-level": 0,
    "log-file": null,
    "mode": "nicehash",
    "pools": [
        {
            "url": "pool.supportxmr.com:5555",
            "user": "WALLET",
            "pass": "PROXY",
            "variant": -1
        }
    ],
    "retries": 2,
    "retry-pause": 1,
    "reuse-timeout": 0,
    "user-agent": null,
    "verbose": false,
    "watch": true,
    "workers": true
}
```

In both cases, I can not get the proxypanel to connect to the xmrig-proxy API.
I use xamp to run proxypanel locally, on the same computer that run xmarig-proxy.
In the proxypanel web interface I use local IP 192.168.0.2:6666 once the SAVE button is pressed, the page changes, but the xmrig-proxy data does not appear.
proxypanel web interface works, but it does not receive data from xmrig-proxy.
