I have simple code above when running locally everything is OK i can retrieve html code and do staff , but when i compile and place on a server i always receive Unable to connect to remote server error. Program is started under administrator account, and server browser (IE, FF) can open page that i request in consloe application, also i try to turn off firewall, again same error. I'm not sure what permissions are making problems i think i already try everything i can thing of.. Any suggestion...

Answer 1

In this case seems problem is slow/bad internet connection on the server. I just put code in loop if error unable to connect to server occur then run same code again (2 to 5 times), and usually from 2 to 3 times code will connect to server receive data and do the rest of the job. Thanks for the help.
