health-check failing during blue-green deployment

2

I believe it’s a Phoenix app. I have two guesses!

  1. Your health check port should not be 8080. Try removing that from your toml check section. Our proxy verifies the “external connection” (meaning 80 for http and 443 for https)
  2. Sometimes Plug.SSL can be :melting_face:. See: Phoenix http health checks - #2 by andykent

I believe there’s also other example folks adding health check on their phoenix apps here at community, free free to search for more examples.
