accepted ip 0.0.0.0
Sometime notice that hash reports a rate of 0.00 and then directly after I see a bunch of accepts but that the ip is 0.0.0.0 but of course there can be no host with an ip as such in the xmrig clients. The proxy itself is however defined to listen on all addresses.

"bind": [
        {
            "host": "0.0.0.0",
            "port": 3333,
            "tls": false
        }
    ],
