The IP gateway address is 
not set correctly.
Enter the correct IP gateway address if connected to a proxy 
server or a web server through an IP gateway.
The subway mask is not set 
correctly.
Enter the correct subway mask that matches the operating 
environment.
The DNS server address is 
not set correctly.
Check the DNS server address.
The DNS server address 
cannot be resolved.
Set the DNS server for resolving addresses.
• When using a proxy server:
Enter the DNS server address for resolving the proxy 
server address.
• When not using a proxy server:
Enter the DNS server address for resolving the recipient 
addresses.
The address to bypass proxy 
server setting is incorrect.
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.
The connected server or 
proxy server are down.
Check that the server or proxy server you wish to connect to 
is operating normally.
The network drops out or is 
disconnected.
Check the network cable connections. A spanning tree 
environment is recommended to construct a strong 
environment against network interruptions.
Cannot communicate due to 
the load on the server 
application.
Wait a while and try again.
Nothing is displayed on the 
control panel but an error 
occurs.
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.
Cannot connect due to proxy 
server, firewall, or web server 
access restrictions.
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)
