Error during Vaultwarden Install on Eletric Eel RC2

Hi guys, recently I migrate to Eletric Eel RC2, but I faced some issue during the vaultwarden install (fresh install)

It can’t connect to postgree apparently

it shows a lot the error below
“[vaultwarden::util][WARN] Can’t connect to database, retrying: DieselCon.”
“[CAUSE] BadConnection(connection to server on socket "@postgres/.s.PGSQL.5432" failed: Connection refused\n\tIs the server running locally and accepting connections on that socket?”

This error shows during the initial setup.
Idk what can cause this… I have other services (like immich and firefly) that uses postgre too and both works fine.
