·
Only Proxy server shows S (=success)
: The Lisa is configured to use a proxy server, but there is
an issue with the configuration of the proxy server. To resolve this issue, consult your network
administrator.
·
None of the connection tests show an S (=success)
: The Lisa has no internet connection. Check
the IP settings of the Lisa, take special note of the proxy server settings (see instructions above).
Verify the network using a different device on the same network connection. If the settings in the Lisa
are correct and the other device has a working internet connection, the router may restrict internet
access to devices with a specific MAC address, consult your network administrator.
·
Only SW (=software) update server shows S (=success), all other tests show something else
(F, E, or N)
: Only port 80 is available to the Lisa, all other ports are closed. Check the settings in the
. If Device portal is used to manage the Lisa, replace 'Device
portal on port 9999 (old platform)' in the general settings for 'Device portal' to use port 80 for all
services.
·
Config server and SW (=software) update server show S (=success), but Monitoring server
shows F (=failure)
: The Lisa uses port 4444 for the monitoring server, but that port is closed. Check
the settings in the firewall, see
. If Device portal is used to manage the
Lisa, replace 'Device portal on port 9999 (old platform)' in the general settings for 'Device portal' to
use port 80 for all services.
·
Config server shows N (=not applicable)
: The Lisa is configured to use a fixed configuration and
will not apply changes from the configuration server (e.g., Device portal or Streamit's Audio
Distribution Platform)

Ports used by Lisa devices
For correct operation of the Lisa on networks with restrictions on incoming or outgoing traffic, TCP
traffic needs to be allowed on specific ports. This section specifies which ports need to be open for the
Lisa to function properly. Two sets of ports are discussed, both should be considered:
·
Ports used for device-related activities (configuration, monitoring, etc.)
·
Ports used for streaming audio
In addition, all Lisa devices will try to connect to the activation server during startup until the activation
succeeds (see
). Regardless of the configuration platform (if any), the device must be
allowed to reach the activation server. Once activated, the device will no longer try to connect to the
activation server:
activate.streamit.eu, port 80
In all cases the Lisa initiates the connection to the outside, requiring permission for outbound TCP
traffic only. Only when Telnet is used from outside the local network, an inbound TCP connection on
port 23 of the Lisa should be allowed. See
for more information.
