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

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?

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

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?

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.
