Site is not responding

I have a Remix app with the default config:

app = "resume-studio"
kill_signal = "SIGINT"
kill_timeout = 5
processes = []

[build]
  builder = "heroku/buildpacks:20"

[env]
  HOST = "0.0.0.0"
  PORT = "8080"
  PUPPETEER_SKIP_CHROMIUM_DOWNLOAD = "true"

[experimental]
  allowed_public_ports = []
  auto_rollback = true
  cmd = []
  entrypoint = []
  exec = []

[[services]]
  http_checks = []
  internal_port = 8080
  processes = ["app"]
  protocol = "tcp"
  script_checks = []
  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"

  [[services.ports]]
    force_https = true
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 0
    timeout = "2s"

I can deploy it just fine. There’s no error in the logs, the start command is successfully ran (giving Remix App Server started at http://localhost:8080 (http://0.0.0.0:8080))

But the site can’t be reached (no response).

Any idea what could be the problem?

(The exact same app was running as expected a few hours ago, just before I deleted it and recreated it for testing purposes)

EDIT

It’s now working. Seems that the problem was the deletion/re-creation of the app, Fly needed some time.
