SMS not working from Servoy

Hi All ,

I am using Servoy 7.4.2 . I am sending a SMS from Servoy to SMS broadcaster . This will finally fire an SMS . But When I am trying to execute the HTTP post request , it is throwing the exception . Please find the Servo log below :

java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 307 Redirect" 
    	at sun.net.www.protocol.http.HttpURLConnection.doTunneling(Unknown Source) 
    	at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(Unknown Source)

When I am trying to send sms directly from SMS broadcaster in my local machine it is working fine . It is also working fine from Servoy in other person local developer . It is also working fine from Servoy client.Please provide your suggestion on this . Why it is not working in local machine from servoy ? .
