Can't load the Admin UI


I’m trying to set up a simple keycloak production configuration on a Windows 2022 server (every external components that will use keycloak will be on the same server).

I followed the “Configuring Keycloak for production” guide.
My parameters are specified on the start command. Here is the start command console output :

kc.bat start --optimized --https-certificate-file=D:\\certificats\\\\PEM\\ --https-certificate-key-file=D:\\certificats\\\\KEY\\ --hostname=LWSIG01 --db-url-host=localhost --db-username=esign --db-password xxxxxxx

The initial administrator credentials are set as env variables.

I open the UI with a local browser (https://lwsig01:8443/) but when i try to access the Administration Console, i’m bloqued on the “Loading the Admin UI” screen.

I havn’t any error on my browser console.

Can you help me to find what i missed plz ?

See this umbrella issue, perhaps it will help you:

Thx for your answer Dasniko, i take a look.

I found the issue.
I entered a hostname in upercase in my start command. With the hostname parametre in lowercase, i can now access the admin UI.
