cannot access arduino yun web

Hi! After reset al arduino a lot of times I can get it to the web and configure it: connect to my wifi, localip, and rest=open. I tried a sketch with simple digitalwrite(12,1); digitalwrite(11,1) and my leds light up!. But when I get the browser and http://localip/arduino/digital/12/1 dont work. Also my start function dont work. Then I think that rest is not working somebody hava a idea?

Thank you!
