      You're using Etherpad in 'dimension' mode (`matrix_etherpad_serving_mode: dimension`), which tries to host Etherpad at the Dimension subdomain - `{{ matrix_server_fqn_dimension }}`. However, this isn't possible because Dimension is not enabled. To resolve the problem, either enable Dimension (`matrix_dimension_enabled: true`) or switch Etherpad to standalone mode (`matrix_etherpad_mode: standalone`) and have it served on its own domain (`{{ matrix_server_fqn_etherpad }}`).
  when: matrix_etherpad_enabled | bool and matrix_etherpad_mode == 'dimension' and not matrix_dimension_enabled | default(False) | bool
