The default SSL/TLS version for the device is TLS1.2. If TLS1.2
is not supported in the server that the device is connecting to,
enable TLS1.1 in the device.
In the environment using the proxy server, you must
configure the device to use the proxy server to connect to a
desired web server. Make sure that you configure the settings
to use the proxy server.
In an environment that does not use a proxy server, such as
when connecting to an intranet, do not make the settings to
use the proxy server.
When the settings to use a proxy server are configured, you
cannot connect to a desired web server only if the IP address
of the proxy server is correct. Set the correct IP address of the
proxy server.
Set the user name and password on the device that allow
connection to the proxy server.
The default SSL/TLS version for the device is TLS1.2. If TLS1.2
is not supported in the server that the device is connecting to,
enable TLS1.1 in the device.
Symptom
When 0 (zero) is prepended to the head of value for the IPv4
address (for example 192.0.2.010), the connection fails. Do
not prepend 0 (zero) to each value of an IPv4 address.
When you cannot access the device when specifying the link-
local address, append a scope ID to the address.
For example, when you use Internet Explorer 11 on Windows
10 to access the address "fe80::203:baff:fe48:9010", you
must append the Ethernet adapter local area connection
number (for example, 8) for Windows 10. In this case, the
address becomes as follows: fe80::203:baff:fe48:9010%8
When the device cannot connect to Windows OS that
supports IPv6, assign a static IPv6 address to the Windows
OS.
Then, register the IPv6 address on the device as the host
address to allow communication.
Remedy
Address (port) restriction
SSL restriction
User access restriction (including access right levels)
Content block
Scheme restriction (cannot use HTTP etc.)
Transfer data size restriction
Method restriction (cannot use POST etc.)
HTTP header restriction (only accepting specified browsers
etc.)
Time restriction (only available during a specific period of
time etc.)
