If you are unable to connect to the management GUI from your web browser and received
a Page not found or similar error, this information might help you
resolve the issue.

Consider the following possibilities if you are unable to connect to
the
management GUI:
- You cannot connect if the system is not operational with at least one
node online. If you know the service address of a node canister, either
use the service assistant to verify that the state of at least one node canister is active,
or if the node canister is not active, use the LEDs to see if any node canister state is
active. If there is not a node canister with a state of active,
resolve the reason why it is not in active state. If the state of all node canisters is
candidate, then there is not a clustered system to connect to. If the node state is service, see the topic that contains information
about fixing node errors.
- Ensure that you are using the correct system IP address. If you know the service address of a node canister, use the service assistant
to gather information about the node canister and the clustered system. You can also use the
USB flash drive to obtain the system IP
address from the data that is returned.
- Ensure that all node canisters have an Ethernet cable that is
connected to port 1 and that the port is working. Use the Ethernet LEDs to
understand the port status.
- Ping the management address to see if the Ethernet network permits
the connection. If the ping fails, check the Ethernet network configuration to see if there is
a routing or a firewall issue. Ensure that the Ethernet network configuration is compatible
with the gateway and subnet or prefix settings. Ensure that you have not used the Ethernet
address of another device as the management address. If necessary, modify your network
settings to establish a connection.
- If the system has management IP addresses assigned to both port 1 and
port 2 it is possible that these are connected to independent Ethernet networks. Ensure the
address you are using is accessible from the network port to which your management workstation
is connected. Try using the alternative management IP address.
