Make sure that your client configs match the server configs.

Had same problem, there is a bug in cpw.mods.fml.common.network.FMLPacket.makePacketSet

 

Arrays.copyOfRange takes end of range as last parameter, not length, so insted of

chunks[i] = Bytes.concat(new byte[] { UnsignedBytes.checkedCast(type.ordinal()), UnsignedBytes.checkedCast(i), 
UnsignedBytes.checkedCast(chunks.length)}, Ints.toByteArray(len), Arrays.copyOfRange(packetData, i * 32000,  len));

there shuld be

chunks[i] = Bytes.concat(new byte[] { UnsignedBytes.checkedCast(type.ordinal()), UnsignedBytes.checkedCast(i), 
UnsignedBytes.checkedCast(chunks.length)}, Ints.toByteArray(len), Arrays.copyOfRange(packetData, i * 32000, i * 32000 + len));

 

Here is a quick patch I made, install it after forge like any jar mod:

Not sure if you need it on both client and server (I guess yes) but for me it fixed the problem after putting it only server side.

Sry my fix is not working, I just launched wrong copy of minecraft

Unfortunately this file is signed so I cannot modify, or I am just too stupid to find a good solution, need to wait for forge team

FML contains the fix. Just need to push it to forge.

We are having the same issue, just tried to update our server to 1.4.7 and can't log in.  Works fine ssp, looking forward to the fix!
