A guess that you may want to redirect 443 north to 8080 south.

[experimental]
-  allowed_public_ports = [80, 443]
  auto_rollback = true

[[services]]
-  http_checks = []
-  internal_port = 80
+ internal_port = 8080
  processes = ["app"]
  protocol = "tcp"
  script_checks = []
  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"

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

If not, check if the health checks for 44380 are passing: flyctl status --all -a <app-name> (ref).

Not required but, you can also omit all mentions of process = ["app"] (if you are not running a Fly multi-process app), which is anyway the default.
