Portable Why Cant I Connect? v1.12.4




“Why Can’t I Connect?” is a network diagnostic tool that makes it easier to resolve TCP/IP connection errors. Use it to diagnose connections to common server types (Microsoft SQL Server, MySQL Server, FTP, SFTP, IMAP, POP3, SMTP, IRC, LDAP, Usenet) and create generic TCP/IP clients and / or servers. Maybe a firewall is blocking the requested port, the port isn’t listening, DNS isn’t returning the expected address, DHCP hasn’t supplied a local IP address, etc.

“Why Can’t I Connect?” will show the error code, error description, time, date, and where the error occurred. Diagnose and repair your home and business network with this user friendly tool. “Why Can’t I Connect?” is currently supported in Windows and Linux. Windows install executables, rpms, and debians are available as well as source code.

There is language support for Chinese (simplified character set), Czech, Danish, Dutch, English, French, German, Hindi, Italian, Polish, Portuguese, and Spanish.

Release Notes:

1. Fixed a bug where the "Server Send" dialog and the "Server Shutdown" dialog where clipping the display of the connected socket handle.
2. Removed the WiFi connect option. Lacking time and hardware to support this in all operating systems for all routers, I will reintroduce this option when possible (check the README file to restore this option at it’s current state while compiling.)
3. Updated the MinGW compiler, wxWidgets, and OpenSSL versions for the Windows binary release (this and all future releases are no longer compatible with Windows XP.)
4. Added a Raspbian / armhf debian binary release.
