IPv4 and IPv6 Connection Problems
The possible causes and remedies for problems when using an IPv4 or IPv6 address are as
follows:
Unable to connect using an IPv4 address
Unable to connect using an IPv6 address
Cannot communicate because
of overloading of the server
application.
Wait for a while and try accessing again.
An error occurs that is not
displayed on the control panel.
Even though an error occurs during background
processing, no message appears on the control panel.
Display the [Not found] screen or print the Job History
Report to confirm the result.
Cannot access the proxy server,
firewall, or Web server as a
result of access control.
The following types of access control are used. Confirm
the configured access control.
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.)
Symptom
Remedy
When 0 (zero) is prepended to
the head of a value for the IPv4
address (for
example:192.0.2.010),
connection fails.
Do not prepend 0 (zero) to each value of an IPv4
address.
Symptom
Remedy
You cannot connect to the
machine with the link-local
address.
When you specify the machine's link-local address, a
scope ID must be appended to the address. For
example, when you use Internet Explorer 11 on
Windows 7 to access the address
"fe80::203:baff:fe48:9010", you must append the
Ethernet adapter local area connection number (for
example, 8) for Windows 7 to the address as follows:
fe80::203:baff:fe48:9010%8
The machine cannot connect to
a computer running Windows
OS that supports IPv6.
Assign a static IPv6 address to the computer running
Windows OS that supports IPv6. Then, register the IPv6
address on the machine as host address to allow
communication.
