[1.7.10-1492] Unexpected packet during modded negotiation

Posted September 16, 201510 yr

Sup!

I have an annoying problem for almost a year with no success in fixing:

[20:39:00] [server thread/INFO]: Suurin left the game

However, let me explain it in-depth!

Initially I played w/ friends via 'Open to LAN' feature, where I routed port from router to my PC (I have real static WAN IP).

Later I moved minecraft forge server to my new home server pc and it was perfectly working for a while. Later one of my friends has started to expecting problem with logging into server ([20:33:06] [Netty Client IO #0/INFO] [FML/]: Unexpected packet during modded negotiation - assuming vanilla or keepalives : net.minecraft.network.play.server.S00PacketKeepAlive).

We did almost everything that we was able to do:

Our mods, configs and forge versions are identical
We tried to run identical versions of JVM - it didn't help
Host (me) and friend, that have connection problem, changed ISP's (we're living in different towns)
Clean server and OS reinstall didn't help too
Today another player got the same error

I checked a lot of threads with the same error but in most cases they are trying to log into forge server with vanilla client while we are playing with forge client on forge server.

However, other players are still able to log onto server and play without problems.

There is some logs, maybe someone can help us with this issue.

Client

fml-client-latest.log

Server

fml-server-latest.log

Pls no grammar hammer me, English isn't my native language but I tried my best.

Regards, Andy.

I suggest you try this out on a computer in the same network. Because from the looks of it, this is just a network problem, either on your end or the client's end.

Yeah, I was pretty sure about network, but I tried to host server on my PC instead of home server PC, and my friend tried to play from his GF;s laptop - same issue. It won't disappear even after we both changed our ISP. From now, only Hamachi works for those, who experiencing this issues.

However, we have abosolutely no problems in another games (a LOT of them), and WinMTR shows no packet loss. This is why now I don't think that it's a network problem.

The fact that it works fine with Hamachi shows pretty clearly that this is not the Game's fault.

So this is software problem somewhere, right?

It can be. It can also not

I think if I had hardware fault it should affect other applications too.

Well, anyway, thanks for advices, seems we're stuck with Hamachi for now.

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Dealing with modded server issues can be a real headache been there! At least you can keep your look stress-free with a fresh low taper fade.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
