Only first instantiated Client object can execute RPCs

Only the first instantiated Client object can execute RPCs. Client object created after the first one raise exception when RPC method is invoked through it.

client1 = KRPC::Client.new.connect!
puts client1.space_center.ut #=> 9463.840156254686
client1.close

client2 = KRPC::Client.new.connect!
puts client2.space_center.ut #=> Exception: RPC call attempt while not connected to server -- call Client#connect first

RPC methods are bound to a single Client object. RPC method use the Client object that was in scope during that method (dynamic) creation. When second Client object is instantiated, RPC methods accessed through this object execute RPC calls using the first Client object's connection.
