    Get "Connection Refused" when trying to access GDC client for first time

    • Product: Voyager
    • Product Version: 8.1.2

    Problem Symptoms

    • After accessing GDC client and before Operator ID/password prompt, message "Connection Refused."
    • GDC has not been used before
    • Other clients do not give "Connection Refused" message


    This error may occur if the port for GDC is not open.


    1. Determine which port is being used for GDC. Usually xxx15 in a port series; for example, in a 70xx port series, GDC port would be 7015.
    2. From command prompt on client machine, test port is open using telnet: telnet localhost xxx15 (where xxx15 is the GDC port determined in step 1).
    3. If the response is "Connected to localhost." then the port is open and another cause is responsible. Please open a support incident with Voyager Support.
    4. If the response is "Connection Refused" check that that port is open in the firewall. (If server is hosted, see "How do I add an IP address to access Voyager through hosted server firewall?"
