Unable to connect

The "Unable to connect" status message displays in the Hub Status pane when the Hub is included in the known Hubs list but the Hub is offline or the network is unreachable. For example, a firewall issue or other network issue could be blocking access from the Manager to the Hub.

Problem: TCP port is not configured correctly

The Hub cannot be reached via the TCP port (18574 by default) that is used by the AnywhereUSB Manager and is listened to by the Hub. Both the Hub and the Manager must be configured with the same TCP port in order for the Hub to connect to the client.

Resolution

Verify that the TCP port settings match for the Hub and the client.

• Hub: See AnywhereUSB Configuration page.
• Client: Verify the TCP port on your computer.

Problem: Hub is offline

The Hub could be powered off.

Resolution

Verify that it is connected to a power source and turned on.

Problem: Invalid Hub certificate

In some situations, the Hub certificate may become invalid. The Hub and the AnywhereUSB Manager must have matching certificates to be able to communicate. If the certificates do no match, the Hub and the AnywhereUSB Manager cannot communicate and a red X displays next to the Hub name in the Manager.

Resolution

For more information, see Manage Hub credentials and Invalid Hub Certificate.

Problem: Hub has a different IP address

The device is no longer connected or has been moved to another network segment. The AnywhereUSB Manager does not discover Hubs that are not on the same network segment as the client.

Resolution

Add the Hub to the list of known Hubs. This ensures that the AnywhereUSB Manager can connect to the Hub, even it is on a different network. See Manage the list of known Hubs.

Note If you add a Hub to the list of known Hubs and you have the Hub autofind feature enabled, this may result in a duplicate connection for the same Hub. See Duplicate Hub.

Problem: Network issue blocking access

You should verify whether a network issue is blocking access to the Hub.

Attempt to ping the Hub:

• If you have a firewall that blocks TCP ports but allows ping, you will see successful pings but still not be able to connect. Contact your system administrator to verify that your firewall is not blocking TCP ports.

• If you can ping the Hub and are able to connect, a network issue does not exist and a different issue has occurred.
• If you cannot ping the Hub, check the configuration of the PC, and the Hub network settings, including firewalls and the network between them.

Problem: Duplicate Hub

If you have added a Hub to the known Hub list that is on same network as your computer, and you have the Autofind Hubs feature enabled, the Hub is found twice. The AnywhereUSB Manager attempts both connections, and the first one to connect will connect as expected. The second connection is discovered as a duplicate, and the Manager closes that connection and red X displays.

For more information, see Duplicate Connection.

Resolution

The Hub added to the known Hubs list is considered a duplicate Hub, and should be removed from the known Hubs list.

Problem: Old version of AnywhereUSB Manager

In same cases, a Hub cannot connect to an older version of the AnywhereUSB Manager.

Resolution

Update to the most recent version of the AnywhereUSB Manager. See Install the AnywhereUSB Manager.

Problem: Incompatible Hub

In some cases, the Hub firmware is old and must be updated to ensure that it can connect to the AnywhereUSB Manager.

Resolution

Update to the most recent version of the Hub firmware. See Update system firmware.
