GUI login page does not open

The management GUI is accessible through the following URL after the installation: https://<ip or host name>.

If the GUI login page does not open, try out the following:

Issue the following command to verify the status:
```
systemctl status gpfsgui
```
Check the status of java components by issuing the following command:
```
netstat -lnp | grep java 
```
There can be more lines in the output as given in the following example. The GUI does a self-check on 443 and is automatically redirected to 47443:
```
tcp6 0 0 :::47443 :::* LISTEN 22363/java
tcp6 0 0 :::127.0.0.1:4444 :::* LISTEN 22363/java
tcp6 0 0 47080 :::* LISTEN 22363/java
```
Note:
- The IBM Storage Scale GUI WebSphere® Java™ process no longer runs as root but as a user named scalemgmt. The GUI process now runs on port 47443 and 47080 and uses iptables rules to forward port 443 to 47443 and 80 to 47080.
- The port 4444 is used by the GUI CLI to interact with the GUI back-end service. Other ports that are listed here are used by Java internally.
If you find that the port 47443 is not opened by WebSphere Liberty, restart the GUI service by issuing the systemctl restart gpfsgui command. The GUI uses the default HTTPS port 443. If some other application or process listens to this port, it causes a port conflict and the GUI does not work.
