Hi,
Everything looks normal from your debug log....... and the debug tool was able to successfully connect to the Convivea server, make a HTTP request, and get a valid response. Since you are saying that Bit Che is unable to do the same (updates say connection timedout), then you must look at your Firewall in both NOD32 and Windows Firewall because one of them is blocking Bit Che. A firewall or other security program is the *ONLY* reason why the debug tool can work normal and Bit Che does not, since they use identical internet connection code.
smart security also has application control other than just the firewall, so look really close at that, or if you have ANY other security programs, look at them too..
