    Hi, we bought a plugin that works fine, but it spams the console with this:
    13.08 20:58:39 [Server] WARN Could not contact BukkitDev to check for updates. 13.08 20:58:36 [Server] WARN at java.lang.Thread.run(Thread.java:745) 13.08 20:58:36 [Server] WARN at net.minecraft.server.v1_8_R3.MinecraftServer.run(MinecraftServer.java:556) 13.08 20:58:36 [Server] WARN at net.minecraft.server.v1_8_R3.MinecraftServer.A(MinecraftServer.java:653) 13.08 20:58:36 [Server] WARN at net.minecraft.server.v1_8_R3.DedicatedServer.B(DedicatedServer.java:374) 13.08 20:58:36 [Server] WARN at net.minecraft.server.v1_8_R3.MinecraftServer.B(MinecraftServer.java:722) 13.08 20:58:36 [Server] WARN at org.bukkit.craftbukkit.v1_8_R3.scheduler.CraftScheduler.mainThreadHeartbeat(CraftScheduler.java:350) 13.08 20:58:36 [Server] WARN at org.bukkit.craftbukkit.v1_8_R3.scheduler.CraftTask.run(CraftTask.java:71) 13.08 20:58:36 [Server] WARN at joehot200.h$27.run(Main.java:1190) 13.08 20:58:36 [Server] WARN at joehot200.UDPClient.a(UDPClient.java:56) 13.08 20:58:36 [Server] WARN at java.net.DatagramSocket.send(DatagramSocket.java:693) 13.08 20:58:36 [Server] WARN at java.net.PlainDatagramSocketImpl.send(Native Method) 13.08 20:58:36 [Server] WARN java.io.IOException: Operation not permitted

    It seems that you guys might be blocking some connection it's trying to do. Is there anyway to fix this?

    Forum support is faster for me. And we got this server months and months ago. I tried fiddling with the plugin's configuration and googling how to fix this, but it seems its the host's problem because it's attempting to block connections that the plugin is trying to send.

    You need to send in a ticket to the general department so they can take a look at the server and see what the problem is @TylerB is staff of mcprohosting

    I get support faster from the forums than tickets for me so I'm trying to get support here first. I did this last time and got a reply very fast. Hopefully there's something that can be done. Nothing bad comes out of those errors but it gets very spammy and annoying.

    @PimpinPSP Are you confident this is a the server trying to open a connection and not a plugin? It's possibly an incorrect updater in the plugin, is it custom?

    It's the plugin. I know I'm not supposed to decompile it but I was paranoid why the plugin was attempting to establish a UDP connection. In the error, it says:
    [Server] WARN at org.bukkit.craftbukkit.v1_8_R3.scheduler.CraftTask.run(CraftTask.java:71)
    [Server] WARN at joehot200.h$27.run(Main.java:1190)
    [Server] WARN at joehot200.UDPClient.a(UDPClient.java:56)

    UDPClient is a class file in the plugin (called UDPClient.class inside the jar file), which is being called from the main class of the plugin (h.class in the jar file). Looking into UDPClient.class, it's trying to connect to an external IP, sending a small string message saying "Hi!". Possibly to reduce piracy. But the host is blocking the UDP connection so it's spamming the error in the console saying it wasn't permitted to do that.

    @PimpinPSP Firstly, who called their main class a one character name lol. Secondly, what is the plugin called? And where does the ip point to, is it a curse website?

    Many plugins do. I can't get the IP address right now, but it started with something like 42, definitely not curse, bukkit, or spigot. The plugin is called AntiAura.

    Wow that's quite a smart plugin right there. I have to go now, try sending a PM to the dev and see what they say. Sorry for the lack of help but I'm in rush. Bye

    If that's the case, then I'll have to ask our system admin team to fix it. Can you link me to download the plugin?

    The plugin is premium so you would have to buy it in order to download so linking it to you is illegal. And decompiling is illegal too, i know, but i didn't touch anything. however, i can give you the ip thats being blocked

    There was no problems with older builds. Newer builds introduced the new UDPClient.class file that wants to send connections which spams the server console.

    Ahh okay. I have not used it since April. Me and one of our system admins will load it up and take a look. If we can fix it, we will. :D
