bigip_ucs_fetch module failing to download ucs file

When trying to create and download a ucs file, the bigip_ucs_fetch module is failing if the ucs file is not already created on the guest. The error is "read operation timed out", even after adding a timeout for 7200 seconds the failure is seen. If the ucs file is created first on the box, the module works fine.Please help.
