liveview application auto-terminates itself at start up

Hello,

I have a liveview application that terminates at start up with this message:
** (exit) :terminating
(kernel 10.2.6) application_controller.erl:511: :application_controller.call/2
(kernel 10.2.6) application.erl:367: :application.“-ensure_all_started/3-lc$^0/1-0-”/1
(kernel 10.2.6) application.erl:367: :application.ensure_all_started/3

(mix 1.17.3) lib/mix/task.ex:495: anonymous fn/3 in Mix.Task.run_task/5

app is started like this:
$ MIX_ENV=prod iex --sname ‘mdap-webdev’ --cookie ‘webdev observer-10.19.13.143’ -S mix phx.server

Env:
Erlang/OTP 27 [erts-15.2.6] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit:ns]

Interactive Elixir (1.17.3) - press Ctrl+C to exit (type h() ENTER for help)

It compiles without error but from a reason that escapes me it terminates.

Any clues of what could be the problem?

Has anyone had this issue?

Thank you

that’s very little information. There’s probably an error somewhere else in the logs. Maybe you need to increase verbosity (level on Logger config)
