This line in error stack trace is what bothers me
(phoenix) lib/phoenix/endpoint/handler.ex:33: anonymous fn/5 in Phoenix.Endpoint.Handler.init/1
That do not exists in phoenix if I’m not wrong. Could you check in mix.lock what commit mix checked out for you?
I’v checked older tags on github, this Phoenix.Endpoint.Handler is part of 1.3 stuff. Try to delete deps folder and do deps.get again. I think it somehow reads old version stuff and mixing it with code that is checkout from git. Also check what is in mix.lock since some deps could be pulling older version.
rm mix.lock && rm -rf _build/ && mix deps.get --all
Never delete _build without deleting deps and vice versa…
This doesn’t work either
[
{:phoenix, "~> 1.4-rc.2", override: true},
# {:cowboy, "~> 2.4"},
{:plug_cowboy, "~> 2.0"},
_build and deps directories were deleted
I really think we need an SSCCE git repo that we can clone and try ourselves at this point? Really sounds like some kind of wrong setup issue or so…
With the bog standard phoenix 1.4-rc2 setup using cowboy2 it runs without issue, this is the mix.exs file:

}
And that includes the two dependency lines you show as using for phoenix and plug_cowboy, so I really need an SSCCE from you to reproduce it as I can’t seem to be able to… ^.^;
Try to use Elixir 1.7
I’m pretty sure @OvermindDL1 does already, as he usually is on most recent stable usually, if not on master…
Also there is no 1.7. If you consider your elixir version to be the fault, then please provide the full version and which OTP it was built on, such that we can reproduce your environment as close as possible. Also, as you blame the elixir version, have you upgraded or downgraded it? Does the problem go away then? If not, how come blaming the elixir version?
Also you have been asked for a SSCCE, if you had provided it, you probably had some more input and directions for solving your problem.

All standard from a normal phx_new call.
We really really need that SSCCE so we can just git clone ... it and run it ourselves.
Here is another observable. With Phoenix 1.3.3, on Windows, mix phx.new some_name. Set up a dev.exs login. Compile. Mix phx.server. The error happens. It wasn’t happening evening before.
This started last evening EST for me.
Doesn’t have support for Cowboy2 nor does it have any Cowboy2 code, so would need an SSCCE for that too.
As we are trying to debug his app and not yours, I’m not sure if I had answered the question for the config…
Yep, but we haven’t got an SSCCE yet so the best we can do is compare our working versions and see how theirs is different. ^.^
We really need an SSCCE… >.>
Please verify the assumption that nothing changed in 1.3 when doing a phx.new. The errors that I was receiving are very similar to the errors described above.
The 1.3 installer had not changed in a very long time.
Regardless of Phoenix version, if you are using Plug 1.7, then you will require {:plug_cowboy, "~> 1.0"} for cowboy to work.
If you are using Phoenix 1.4, then you can use {:plug_cowboy, "~> 2.0"} or {:plug_cowboy, "~> 1.0"}.
You should be prompted about this when the application starts:
warning: please add the following dependency to your mix.exs:
{:plug_cowboy, "~> 1.0"}
This dependency is required by Plug.Adapters.Cowboy
which you may be using directly or indirectly.
Note you no longer need to depend on :cowboy directly.

The workaround that allows the application to start:
when performing mix phx.new
The mix.lock file pulls in:
“plug”: {:hex, :plug, “1.7.1”, “8516d565fb84a6a8b2ca722e74e2cd25ca0fc9d64f364ec9dbec09d33eb78ccd”, [:mix], [{:mime, “~> 1.0”, [hex: :mime, repo: “hexpm”, optional: false]}, {:plug_crypto, “~> 1.0”, [hex: :plug_crypto, repo: “hexpm”, optional: false]}], “hexpm”},
When the above is replaced with:
“plug”: {:hex, :plug, “1.6.3”, “43088304337b9e8b8bd22a0383ca2f633519697e4c11889285538148f42cbc5e”, [:mix], [{:cowboy, “~> 1.0.1 or ~> 1.1 or ~> 2.4”, [hex: :cowboy, repo: “hexpm”, optional: true]}, {:mime, “~> 1.0”, [hex: :mime, repo: “hexpm”, optional: false]}], “hexpm”},
The server will start.
This situation happens on a fresh mix phx.new with the latest Phoenix 1.3.4 on a fresh Windows 10 machine. Is plug 1.7.1 correct for a 1.3.4 Phoenix?
