Problex with Xively

I have loaded the demo to my C027 and added in a connection to Xively however it seems to hang when I use the modem rather than Ethernet the problem occurs during xi_feed_update(xi_context, &feed); during the read operation. Any ideas? I added the HTTP post and GET in as a test and I also get header errors. I am very new to this so any help is appreciated

1. include "mbed.h"
2. include "HTTPClient.h"

1. include "GPS.h"
2. include "MDM.h"
3. include "xively.h"
4. include "xi_err.h"

1. define XI_FEED_ID 1265594688 set Xively Feed ID (numerical, no quoutes)
2. define XI_API_KEY "5YJ2i0AV0yH9NcU1FL2IcN7SzGEgMDCEEPh3EVrKh7arD6IN" set Xively API key (double-quoted string)

------------------ You need to configure these cellular modem / SIM parameters. These parameters are ignored for LISA-C200 variants and can be left NULL. ---------------- ! Set your secret SIM pin here (e.g. "1234"). Check your SIM manual.

1. define SIMPIN NULL /*! The APN of your network operator SIM, sometimes it is "internet" check your contract with the network operator. You can also try to look-up your settings in google: https://www.google.de/search?q=APN+list */
2. define APN "wlapn.com" ! Set the user name for your APN, or NULL if not needed
3. define USERNAME "????" ! Set the password for your APN, or NULL if not needed
4. define PASSWORD "adaptive" ------------------
