HomeZoom Commander › Troubleshooting
 Connecting to a Remote Screen
  1. Running
    Make sure both Zoom Commander and all desired Zoom Presenter instances are running.
    Every running Zoom Presenter instance is identified by an icon within the Windows taskbar tray area.

    In recent versions of the Windows operating system, Windows hides tray icons automatically after several seconds by default.

    To ensure Zoom Presenter's icons are visible at all times, click the tiny upward pointing triangle next to the taskbar tray area and select the "Customize" option. Locate Zoom Presenter's icon and select the "Show icon and notification" setting next to the icon.


  2. Firewall
    Zoom Commander and Zoom Presenter must have a clear line of communication over the Internet or a local area TCP/IP based WiFi or Ethernet network. Firewall software may block applications or specific TCP port from being accessible. Encountering error #10061 trying to connect a screen in Zoom Commander, indicates a firewall blocked the connection.

    Zoom Commander and Zoom Presenter's installers can add an exception to the Windows firewall to let communication pass-through. If the process fails, please manually review Zoom Commander's and Zoom Presenter's Windows firewall setting.

    Firewalls may also exist within routers.
    In such cases, TCP ports specified using the Zoom Presenter INSTANCE manager must be opened up and forwarded in the router's firewall setup.


  3. IP Address
    A computer on a network may have more than one IP address (number). For example, the computer's local area network may have an IP of "10.0.0.1", while to the internet at large, the same computer may have an IP of "173.194.34.98".

    When specifying a screen's IP address in Zoom Commander, it is important to note which IP to use and if one does not work, use the other.

    For a list of all known local area network IP addresses on a Windows PC, type "cmd /k ipconfig /all" in the Windows start menu's "run" box. For the internet accessible IP address, type "What is my IP" into google.


  4. Routers & Port forwarding
    When using a router, ensure the router's DMZ Host or port forwarding is setup correctly and data is relayed to the correct PC within the network.

 Connection Errors
  1. Screen error #10013
    Permission denied.
    An attempt was made to access a socket in a way forbidden by its access permissions.


  2. Screen error #10053
    The screen has unexpectedly disconnected.
    This may indicate the PC has turned off or no longer has network access.


  3. Screen error #10060
    The connection timed out.
    This may indicate the Zoom Presenter instance or the entire PC is partially stuck (high CPU or network load) or frozen.


  4. Screen error #10061
    Unable to connect.
    This error appears when the connection is blocked by a firewall or router configuration. Under certain network conditions, the error may appear when connecting to a screen that is not currently running Zoom Presenter.


  5. Screen error #10065
    No route to host.
    A socket operation was attempted to an unreachable host.


  6. Screen error #11001
    Unable to resolve address.
    This error appears when the screen instance's address does not resolve. This may indicate an issue with the DNS server or possibly a typo in the address name.


  7. Timed out trying to connect.
    This error may indicate several issues:
    1. There is no running instance of Zoom Presenter on the specified network address.
    2. A firewall is blocking the connection.
    3. The network is overly congested.
    4. The remote PC is overloaded and is unable to respond.

 Zoom Commander Notifications
  1. Playlist file did not contain any valid entries.
    When the current playlist on a Zoom Presenter instance contains playlist entries that reside outside the specified 'Share Path' folder, this message will pop-up to indicate there is an issue. To resolve this issue, specify a new playlist.

  2. This Zoom Presenter instance was probably not executed with the required "/SharePath:[Path]" command line parameter.
    Other than not specifying the "/SharePath" command line parameter, this dialog may appear when trying to add files the playlist with the browse dialog set to a directory that no longer exists. In such a case, clicking the '\' root button bypasses the issue.

  3. The remote schedule could not be read as it contains entries outside of the shared path.
    As a security measure, this dialog pops up when the playback schedule currently set on the Zoom Presenter instance contains entries from outside the specified 'Share Path' folder.
