Hi!
Okay, first please go to the proxy settings and select 2) Proxy Configuration. Then go to 5) Advanced Settings and there you select 2) INX-Dashboard [SHIMMER] Proxy Settings and then please make sure that 1) Enable INX-Dashboard is set for you.
Then go back and select 3) Hornet [SHIMMER] Proxy Settings. Please make sure that your domain is stored with the corresponding port, e.g. example.com:443. Finally, unless you are automatically prompted by the installer, go back and select 4) Proxy Installer from the main proxy menu and then 1) Install/Deploy The Proxy.
Once the process is successful, you can access your Dashboard & API normally using the address set in 3) Hornet [SHIMMER] Proxy Settings.
The options available in 2) INX-Dashboard [SHIMMER] Proxy Settings are only useful if you want to separate the API and the Dashboard, e.g. have the Dashboard running explicitly on a different domain or port.
