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.
If you are unable to connect to the management GUI from
your web browser and received a Certificate expired or
similar error, see Resolving a problem with SSL certificates.
If you are unable to connect

your web browser and received a cipher error, SSL
error, TLS error, or handshake
error or similar error, see Resolving a problem with SSL/TLS clients.
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.
