Hello @hiremama

Thanks for reaching out and providing the logs. In review, we see that it has been working up to '2021-09-22 08:22:15,875 15582 INFO stopped' where we see python related "line" errors.

Do you know what was changed, added, and/or updated on this Suse server on '2021-09-22 08:22:15,875 15582 INFO stopped'?

Please review and provide system logs that are related.

Thanks,
Perry

Hello @hiremama

Thanks for following up, typically when we see this error the ncpa service is not able to listen as it is unable to connect to the network.

Code: Select all

cat /usr/local/ncpa/etc/ncpa.cfg > /tmp/ncpa.txt

And

Code: Select all

sudo ss -tulpn | grep -Ei 'LISTEN|ESTABLISHED' >> /tmp/ncpa.txt

In the config we want to specify the following:

# IP address and port number for the Listener to use for the web GUI and API
#
# :: allows for dual stack (IPv4 and IPv6 on most linux systems) but will only allow
# for IPv6 connections on Windows
# 0.0.0.0 allows for IPv4 connections only on Windows and most linux systems
#
# Default: ip = ::
# Default (Windows): ip = 0.0.0.0
# Default: port = 5693
#
ip = ::,0.0.0.0

Restart the 'ncpa_listener' and view the status:

Code: Select all

systemctl restart ncpa_listener

Code: Select all

systemctl status ncpa_listener

Please send the '/tmp/ncpa.txt' so we can review the configuration and info.

Thanks,
Perry
