It's really hard to help you, if you don't provide the least of information about your configuration. Could you please add the output of the following tmsh commands:

list ltm virtual 
list ltm pool

BTW your HTTP request is not valid (maybe that's the reason why the BIG-IP denies your request). A correct HTTP/1.1 request use spaces and needs a host header.

GET / HTTP/1.1
Host: www.example.com

An HTTP/1.1 without host header does not comply with RfC and the BIG-IP silently drops or resets those requests.
