[1.7.2] Cannot connect to some servers, NetHandlerLoginClient casting exception

[glassjfss]

Using build 10.12.0.997 of forge and trying to connect to 1.7.2 servers. Some servers will connect fine, some will throw the following error: http://i.imgur.com/WZDZ4pp.png

 

Sometimes I'll also get the following in stdout/stderr: Unexpected packet during modded negotiation - assuming vanilla or keepalives : net.minecraft.network.play.server.S38PacketPlayerListItem

 

Connecting to these same servers using an unmodded vanilla version of the game works fine.

 

Any ideas what's causing this?

Interesting, it should not try to do the modded negotiation unles the server tells it that it's modded. Do you have a couple vanilla servers that this constantly happens on that we can test with?

[glassjfss]

Thanks for the reply, Lex.

 

The following 3 all fail consistently but I'm not sure that they are pure vanilla (the last one definitely isn't):

 

188.122.88.131:29049

gods.blynkyland.com:25052

play.mc-hg.com

 

I seem to get less crashes with servers that claim to be vanilla but it still seems random as to which will crash out.

 

Am I even supposed to be able to connect to all 1.7.2 servers with this version of Forge?

I've been running into this exact issue, same error message and all. Works just fine without forge

I am using the .999 build, and still no luck.

The server I'm trying to connect to is: play.multiverse-mc.com

It seems to be on servers that are behind bungeecord, {or similar multi-server proxies}, but only SOME of them.

We're looking into it. connecting to vanilla servers should work just fine.

not sure if it still needed to post servers where it doesn't work,

but having the same issue on:

 

78.46.141.144:25565

 

on the latest version for 1.7.2

i cant connect to my own server its spigot server i think we got problem with bukkit / spigot server its says vanilla on server selection but i use spigot server

[poiihy]

I have the exact same problem. it's kinda random, but it happens more on some servers and less on other servers.

 

Here is the post on the Minecraft forum about it:

That has more info.

Can confirm, build .1001 works
