Issue with services.http_checks in elixir/phoenix deployment

Questions / Help
1

Hey,

I have an application deployed successfully.

I am trying to add a new http health check.

I added services.http_checks at the end of the fly.toml file.

Here is the whole toml file:

app = "black-forest-5489"
kill_signal = "SIGTERM"
kill_timeout = 5
processes = []

[build]
  dockerfile = "Dockerfile.deployment"

[build.args]
  MIX_ENV = "staging"

[deploy]
  release_command = "/app/bin/migrate"

[env]
  MIX_ENV = "staging"
  PHX_HOST = "black-forest-5489.fly.dev"
  PORT = "8080"

[experimental]
  auto_rollback = true

[[services]]
  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"

  [[services.http_checks]]
    grace_period = "20s"
    interval = "5m"
    method = "get"
    path = "/healthz"
    protocol = "http"
    restart_limit = 0
    timeout = "5s"
    tls_skip_verify = true

I see these when I do flyctl checks list

If I have the protocol as http, the check fails with this:
HTTP GET http://172.19.70.218:8080/healthz: 301 Moved Permanently Output: [✓]
In the logs for this I can see this:
[info] Plug.SSL is redirecting GET /healthz to https://black-forest-5489.fly.dev with status 301

I also tried https:
Get "https://172.19.70.218:8080/healthz": http: server gave HTTP response to HTTPS client[✓]

If I call the endpoint from the browser etc, I get a 200 response.

Does anybody know how to resolve this issue?
