Inside the container, var/www/html/logs/error.log doesn't show anything useful:

At the end firefox just shows: The page isn’t redirecting properly. When going to keycloak, under clients -> leantime -> sessions I see the user is logged in. Also under keycloak events I see some LOGIN and CODE_TO_TOKEN event types.
