Problem
Enter the correct IP gateway address if connected to a proxy
server or a web server through an IP gateway.
Enter the correct subway mask that matches the operating
environment.
Check the DNS server address.
Set the DNS server for resolving addresses.
• When using a proxy server:
• When not using a proxy server:
Check whether only the address to bypass proxy is specified.
If the server is accessed using a direct IP address while
specifying an address to bypass proxy in FQDN format, the
registered server does not become an excluded object.
Therefore, an IP address can be used as the bypass proxy
address. Similarly, if the server is accessed using FQDN
format while specifying a direct IP address for the bypass
proxy address, the registered server does not become an
excluded object. Therefore, an FDQN format can be used as
the bypass proxy address.
Check that the server or proxy server you wish to connect to
is operating normally.
Check the network cable connections. A spanning tree
environment is recommended to construct a strong
environment against network interruptions.
Wait a while and try again.
Nothing 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)
