android - HttpURLConnection GET method works in api 22 only in debug -

httpurlconnection method works in api 22 in debug mode, while in other apis works properly. works in approximately in 3 of 4 cases fires exception:

e/http httpurlconnection:﹕ 2015/05/15 13:18:04 failed connect /10.254.254.1 (port 80) after 5000ms 

this code:

try     {         url url = new url(path);         urlconnection = (httpurlconnection)  url.openconnection();         urlconnection.setinstancefollowredirects(false);         urlconnection.setconnecttimeout(5000);         urlconnection.setreadtimeout(5000);         urlconnection.setrequestmethod("get");         urlconnection.setrequestproperty("user-agent", user_agent);         urlconnection.setrequestproperty("content-type", "text/plain;charset=utf-8");           int responsecode = urlconnection.getresponsecode();          mfunctions.addlog(3, "http responsecode: ", integer.tostring(responsecode));           bufferedreader in = new bufferedreader(                 new inputstreamreader(urlconnection.getinputstream()));         string inputline = in.readline();          return inputline;      } catch (malformedurlexception e)     {         mfunctions.addlog(3, "http url: ", e);     } catch (ioexception e)     {         mfunctions.addlog(3, "http httpurlconnection: ", e);     }         {         urlconnection.disconnect();     } 

i tryed use httpok instead of httpurlconnection, time problem same on api 22 , exception:
