Problem with new theme when restart kecloak

Hello I have a problem. I am creating a new theme for the Keycloak login screen.

Step 1. Duplicated the main theme folder of keycloak
Step 2. Rename the duplicate folder to Custom
Step 3. I modify the login styles and template.
Step 4. I assign the new theme to my Realm.
Step 5. I update the page and see the changes correctly.

The problem is that tomorrow, I go back to the application and the login is shown without styles. It shows the changes made in the login template, but the screen looks without styles, what could be happening?

Thank you.!

Keycloak login html response. Styles references not exists.

keycloak_login_response|690x261

Already solved. The references to the styles are missing in the “theme.properties” file of the login.
