Element open a blank page - CSP Error

[Bschalck]

Hy !

My config :

• Nextcloud Nextcloud Hub 9 (30.0.0)
• Element : https://chat.ethicit.fr
• Login with Keycloak : https://auth.ethicit.fr

The issue :

• Connect to NExtcloud
• Click on Element app
• A blank page appears

• log console :
  Content-Security-Policy: Page settings prevented a resource (frame-src) from loading at https://auth.ethicit.fr/realms/kc*****[...]***MlsLw because it violates the following directive: "frame-src 'self' https://kccloud.ethicit.fr https://chat.ethicit.fr blob:"

This a new test server :)

addenda : the issue is only facing if the user has not logged once on element.
If he has already made a connect , element opens in right way.
