IONOS preview before DNS: the checklist that saves cold sweats

TL;DR Create subdomain → point docroot → set APP_URL → smoke `/up` and admin login.

Key takeaways

APP_URL must match the served Host, or assets / redirects break.
Test `/up` and a login POST before sending the link to the client.
Client DNS is the last step, not the first.

I burned enough evenings with vannalec.fr still on Hostinger while the code was already on IONOS. Since then: preview first.

Order

IONOS panel subdomain (allan.albert-nicolas.fr)
Docroot → project public/
.env: APP_URL=https://allan.albert-nicolas.fr
php artisan migrate --force + storage link
Smoke: /up, home, admin login

curl -sI https://allan.albert-nicolas.fr/up
curl -sI https://allan.albert-nicolas.fr/fr
