Problem:
When I specify additional ports on the TightVNC server and attempt to connect to them from a remote machine, the connection always fails and gives the message "Connection has been gracefully closed". The primary port allows access without issues.

Operating Environment:
OS - Windows 7, 64-bit
TightVNC - 2.6, 64-bit
Configuration - Multiple display setup. Using non-standard primary and secondary ports and access control with specified IP ranges (default is Accept).

Remediation attempts:
I have tried uninstalling and reinstalling, and I have tried different port numbers with no resolution. I have also been able to recreate this problem on another machine with only a single display and no software firewall installed.

Other information:
This problem was not present in 2.5.2 or earlier and has appeared only since I upgraded to 2.6.

    Attached logs produced during failure event. Will post normal accept connection (full desktop) later for comparison.

    Error with extra port will be fixed in the next releases of TightVNC.
    Thanks you for your report.
