Arduino Uno + Yun Shield stopped working

I have an Arduino UNO + Yun Shield connected to my Wi-Fi. I was playing with some examples from the IDE Example library. All working fine. I now come back to it and run the same example (i.e. Bridge - > ConsoleRead) and it does not work anymore. The Serial Monitor display "Unable to connect.." a few times. I tried resetting the Arduino and the Yun Shield. I also re-install he Yun firmware. I'm able to successfully connect to it via WiFi and open the Web Console. I can also successfully upload sketches via WiFi. But cannot connect the Serial Monitor. I verify that the Sketch uses Bridge.begin(); Console.begin();

Any suggestions?

I have the exact same issue, guessing either the uno or the shield has had some sort of a hardware failure. Did you resolve your issue?
