Restrictions
This section explains the restrictions that apply while using Internet or intranet
connections.
Internet/Intranet connections
Connection to the Internet or an intranet depends on various settings, including the
destination web server, the used server application, proxy server, and firewall types.
When connecting to the Internet or an intranet using server application software, proxy,
or firewall supplied by another company, the following conditions are required.
• Windows 2000, Windows XP, Windows Server 2003 or Windows Vista operating
system
• Conformance with the following conditions:
– RFC2616: Hypertext Transfer Protocol HTTP/1.1
(Normal connections, SSL connections, Proxy authentication)

Problem
No message is displayed on the control panel even when an
error occurs during execution of background processes.
Display the [Job Status] screen or print a job history report
and check the results.
Check if any of the following access restrictions are set.
• Address (port) restrictions
• SSL usage restrictions
• User access restrictions (including access privileges)
• Content blocking
• Scheme restrictions (for example, HTTP disable)
• Transfer data size restrictions
• Used method restrictions (for example, POST disable)
• HTTP header restrictions (for example, specific browsers)
• Time restrictions (for example, time-limited access)
The iFlow service cannot be used without certificate
authentication. Obtain a certificate for the required machine
and register the certificate on the machine.
Problem
In a proxy environment, the web server cannot be connected
without the proxy server settings. Enter the settings for using
the proxy server.
For environments where connecting via a proxy is not
required, such as connecting to an intranet, the settings
should not be set for using a proxy server.
When setting up a proxy server, the web server cannot be
connected if the proxy server address is not set correctly.
Enter the correct proxy server address.
Register the user name and password on the machine to
grant connection access to the proxy server.
