Remedy
Check the IP address setting. If the IP address has not been set
correctly, specify a fixed IP address or use DHCP or Autonet to resolve
the IP address.
Enter the IP gateway address correctly when connecting to a proxy
server or web server via an IP gateway.
Set the subnet mask correctly, to match the environment in use.
Check the DNS server address.
Select a DNS server that can resolve the address.
• When connecting via the proxy server
Set the IP address of a DNS server that can resolve the address of
the proxy server.
• When not connecting via the proxy server
Set the IP address of a DNS server that can resolve the destination
address.
Confirm whether only addresses that do not use a proxy server are set.
Even if addresses not through a proxy server are specified using the
FQDN, if a server is directly accessed using its IP address, the registered
server is not excluded. Set the address not to use a proxy server.
Likewise, even if you directly specify an address that does not use a
proxy server, if a server is accessed with the FQDN, the registered server
is not excluded. Set an IP address with the FQDN not to use a proxy
server.
Check whether the server or proxy server to connect to is working
normally.
Check the network cable connections. The use of a spanning tree
environment is recommended to create a network environment resistant
to disconnections.
Wait a while, and then access the server again.
