TCP unable to connect
BlitzPlus Forums/BlitzPlus Programming/TCP unable to connect
| ||
| When I start a tcp server with blitzbasic, some people have trouble connecting to the server. I have firewall and portforwarding set up correctly. Some computers can ALWAYS connect to the server and other computers can NEVER connect. Any ideas? |

| Maybe their firewall blocks the port in question? Also some firewalls (company mostly) is set to only accept HTTP traffic so they actually check packet contents for valid HTTP. Case 1 is easy to solve, case 2 requires some kinda tunneling app or code that wraps/unwraps your data packets with valid HTML |

| I've found Windows Internet (WinInet) userlibs to be more reliable than the internal Blitz TCP commands. For an FTP-based example, see: http://www.blitzbasic.com/codearcs/codearcs.php?code=1444 |

| These 2 are not comparably as WinInit is a much higher layer than simple TCP/IP :) |
