deploy opencloud behind external keycloak

[s0rau]

I'm trying to install opencloud behind external keycloak server used as OIDC.
variables are set

  oidc:
    issuer: "https://keycloak.domain/auth/realms/opencloud"
    clientId: "web"
    accountUrl: "https://keycloak.domain/auth/realms/opencloud/account"

keycloak:
  # Internal Keycloak deployment
  internal:
    # Enable internal Keycloak instance
    enabled: false

In the logs i can see this warning

WRN core access token not set line=github.com/opencloud-eu/reva/v2@v2.31.0/internal/http/interceptors/auth/auth.go:248 pkg=rhttp service=frontend traceid=eb21cf587d02e2a7e25f729936fb8f5

I've added ingress nginx with certificate created as secret, the client get the page through https.

In the web client side, the page is broken
