Ruby--How to get input from server without error? (socket.gets.chomp throwing error)

Question

I'm running a server/client program, I keep getting an error I don't understand:

FishClientRun.rb:18:in `<main>': undefined method `chomp' for nil:NilClass (NoMethodError)
Shizuo:FISHGAME2 macowner$ 

However, the code runs once. It actually receives the cards and stores them just fine. When the client comes loops back around and hangs on the get statement incoming = client.socket.gets.chomp. It doesn't like the .chomp. If I take of the .chomp, it hangs like it is supposed to without throwing an error, but then I get the newline character and get bad input for client.input_decision(incoming).

My client:

client = ClientClass.new('localhost', 2012)

while true
    puts "IN WHILE TRUE!!!"
    incoming = ""
    incoming = client.socket.gets.chomp
    puts "INPUT RECEIVED:::::::: #{incoming}"

    client.input_decision(incoming)
end

Here's the server. I think this part is okay:

server = SocketServerClass.new(2012, number_of_players)

number_of_players.times do 
    server.accept_client(server.fish_game)
end
puts "Clients accepted"

server.update_client_cards(server.fish_game)
puts "client cards sent to server"

while true
sleep(10)
break
end

gets will return nil if it encounters an end of file. Presumably, you want to terminate at that point.
