Bridge example problem

Hi there,

I run a Arduino Mega 2560 with a Yun Shield.

I tryed to load the Bridge example, but when I try

curl localhost/arduino/digital/13

I get this response

Could not connect to YunServer 146 Connection refused

I tryed to remove the line "server.listenOnLocalhost();" as suggested in other threads, with no results.

The REST API is open

Also, after a amount of time, the pin 13 goes down (is put up by the setup()) and any request to the REST API is answered black

Try to make a HTTP request directly on port 5555 returns no answer

Someone know how to help?

also having the same problem. anyone figure out how to solve this? thanks.
