certificate not being issued

Questions / Help
2

as mentioned in this forum post it may be related to the port 443 not being configured. i have configured this and my fly.toml file looks like:

[build]

[deploy]
  release_command = "python manage.py migrate --noinput"

[env]
  PORT = "8000"

[http_service]
  internal_port = 8000
  force_https = true
  auto_stop_machines = true
  auto_start_machines = true
  min_machines_running = 0
  processes = ["app"]

[[services]]
  http_checks = []
  internal_port = 8000
  processes = ["app"]
  protocol = "tcp"
  script_checks = []

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

[[vm]]
  cpu_kind = "shared"
  cpus = 1
  memory_mb = 1024

[[statics]]
  guest_path = "/code/static"
  url_prefix = "/static/"

but the certificate is still not being issued.
