Running into a weird problem.
I have an http server running in one app (app2.internal) I want to make requests to from another app (app1.internal) using the internal routing IP. Both apps are serving http traffic with the following services config:
[[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"
From an ssh console inside of app1, app2.internal resolves to an IPv6 address just fine. app1 can ping app2.internal just fine.
If app1 tries to make an http request to app2.local:80, it gets a ECONNREFUSED error.
If app1 sends an an http request to app2.fly.dev:80, it works just fine.
How can I make an http request from app1 to app2 using the internal address?
