be made with the
product or PC.

▶
Cause
The NTP server IP address or
domain name is not correct.
The route to the registered NTP
server is not specified.
The security filter of the product
is enabled.
Depending on the provider,
name resolution is not possible
immediately after registration/
update.
The product is connected via a
network provider connection.
A private IP address is assigned
by the provider.
Remedy
• Check that the setting is correct by
comparing with the NTP server information
you have obtained.
• Execute the ping command to the NTP
server, to make sure that the NTP server
is running.
Check the provider setting and routing setting.
1. In the "Basic configuration page", select
"Advanced settings" - "Configure firewall"
- "Configure IPv4 firewall" screen. Select
both "in" and "out" check boxes in the pass
filter (No. 36 and 37) that allows traffic to
pass through the NTP port (port No. 123)
which are displayed at the bottom of "IPv4
static IP filter list".
2. Set the security level to 6 or 7 (page 103).
Retry after a while.
If the product is connected via a network
provider connection, the netvolante DNS
service is not available. Directly specify the
IP address for connection.
You cannot use the netvolante DNS service
in the environment where no global IP is
assigned to the product.
Troubleshoot by referring to "If you have
forgotten the password" (page 161).
