v2.4.3 attached every stack container to the `coolify` network so
Traefik could reach the public container. But that network also hosts
coolify-db (alias `postgres`) and coolify-redis (alias `redis`).
Docker's embedded DNS resolves unqualified hostnames to the first
container with that name on the network, so once Twenty's
`postgres-<uuid>` joined the coolify network, Twenty's connection
string `postgres://postgres:5432/...` started resolving to coolify-db
and auth-failing in a tight restart loop.
Coolify's own pipeline only attaches the proxied container — filter
by the `traefik.enable=true` label so internal stack members (db,
redis, worker) stay isolated on the project network.
