Problem reconnecting to same match

Hello, I've found a little annoying problem and I don't know if is my code or a bug but in some sites I've read it's a bug since 5.1.

When in a game I disconnect of a match and later try to reconnect to the same match an exception comes trough.

If I try to connect to other match it connects perfectly.

I'm using unity 5.3.1

This is where I read that is a bug:
