Cannot connect to Server after dying in Portal (also on Realms)

I got killed by a zombie pigman exactly as I went through a portal. Once that happened, the respawn button wouldn't do anything. So I restarted the client, and when I try to log back into the realm, I get the following error every time:

Connection Lost:
Internal Exception: io.netty.handler.codec.DecoderException:
java.lang.IndexOutOfBoundsException: readerIndex(35) + length(8)
