From my observations, this happens when you cannot connect to the host of the lobby. When you don´t get send any data by the host, your client thinks that the lobby is closed and says that the host left.
As speed2 says, logs would be nice, but I am 90% certain it´s a connectivity issue.
From log:

You are trying to join the game and your client wasn´t able to map your port. This is definitely a network problem in my oppinion ( bear in mind, I am inexperienced in reading those logs, so I might be wrong ).
Have you checked if UPNP is activated in your client and all the usual networking remedies? ( port forwarding, switchfing from wifi to cable, etc.? )
