Error -27796: Failed to connect to server "storage.conduit.com:80": [10060] Connection timed out

We successfully installed VTS in Windows server 2003 SP2, where controller is installed.
Usedbelow code in Vuser_Init section.

lr_load_dll("vtclient.dll");//------------------------------------------
ppp = vtc_connect("10.107.1.179", 8888, VTOPT_KEEP_ALIVE);
lr_output_message("******************** The VTS Handle is : %d", ppp);
//------------------------------------------
When we ran the script for 5Vusers with X iterations we found 2 errors as

Error -27796: Failed to connect to server "storage.conduit.com:80": [10060] Connection timed out

But data is writing to VTS table for all 5Vusers successfully

Any suggessions or thoughts?
