Sometimes i received this error code for HTTP requests i have made, searching the SDK help, i got some documentation for this error:
Trying to check my URL from an Internet Browser,, it is successfully working.Code:HttpExampleClient.exe reports error -5120 This error indicates that the URL cannot be resolved to an IP address. This is usually caused by a problem with DNS; either the location of the DNS server is incorrectly specified or there is no DNS server. If using a statically allocated DNS address, check that the value in your comms database's LANService table is correct for your network.
Trying to ping on this URL, it is working also.
I have no idea actually, but i wonder if someone can help me, Any guidelines or suggestions would be greatly appreciated
