Communication Error, still can connect

Since I've installed LilyPad I've kept getting Communication error when pinging the server, but I still can connect. Yes, I've set throttle to 0, port-forwarded every port that LilyPad uses, but still nothing. You can try yourself - IP: funcademc.tk
My allinone.conf:

Code (text):

{
  "proxy": {
    "bind": {
      "address": "0.0.0.0",
      "port": 25565
    },
    "outbound": {
      "address": "0.0.0.0"
    },
    "servers": [
      {
        "domain": "*",
        "server": "hub"
      },
      {
        "domain": "ph.funcademc.tk",
        "server": "prophunt"
      }
    ],
    "motd": "Funcade Network",
    "playerMaximum": 100,
    "authenticate": true,
    "throttle": 0,
    "tabEnabled": true,
    "localeFull": "The server you tried to connect to is currently full. Come back later.",

    "localeLoggedIn": "You have logged in from another location",

    "localeShutdown": "The server is being restarted. Come back in a few moments."
  },
  "queryTcp": {
    "bind": {
      "address": "0.0.0.0",
      "port": 5555
    }
  },
  "queryUdp": {
    "bind": {
      "address": "0.0.0.0",
      "port": 25565
    }
  },
  "connect": {
    "bind": {
      "address": "0.0.0.0",
      "port": 5091
    },
    "logins": [
      {
        "username": "hub",
        "password": "HIDDEN"
      },
      {
        "username": "prophunt",
        "password": "HIDDEN"
      }
    ]
  }
}

Hope to get this fixed. Using build 68.

By the way, all of the servers are on one machine.

Didn't fix it. The additional domain just auto-redirects to the prophunt server.

Home hosted or on a managed / dedicated server? @StashCat

Home hosted, on Windows

I have figured out how to fix this problem and I would like to make a thread that could be moved to documentation. To fix the error simply download build 56 from here: http://ci.lilypadmc.org/job/Server-Standalone-AllInOne/56/ and set your throttle to 0.

Did not help whatsoever.

I'm sorry about that. It worked for me for a little bit, but then it suddenly went back to normal.

I host myself. Never ran into issues with any other server/proxy software.

Version 7 Update 25

I am also curious how to get a full fix for this problem. The only problems that I have left with lilypad is this communication error and the global tab list.

Thanks @Coelho
