Invoker requires port `:9000`, or else will not work.

[gotoAndBliss]

I'm trying to migrate from POW, but lets give Invoker the benefit of the doubt and greenfield a new app rails create newapp && cd newapp. I did..

gem install invoker

My invoker.ini says..

[whisper]
directory = /Users/mycomputer/Sites/newapp
command = bundle exec rails s

I run sudo invoker setup

I run the app with .. invoker start invoker.ini

Looks like it's booting up!

whisper : => Booting Thin
whisper : => Rails 4.0.13 application starting in development on http://0.0.0.0:9000
whisper : => Run `rails server -h` for more startup options
whisper : => Ctrl-C to shutdown server
whisper : Thin web server (v1.6.3 codename Protein Powder)
whisper : Maximum connections set to 1024
whisper : Listening on 0.0.0.0:9000, CTRL+C to stop

But... curl whisper.dev -> Operation Timeout. Strange. https://0.0.0.0:9000 -> This site can’t provide a secure connection 0.0.0.0 sent an invalid response. Weird. http://0.0.0.0:9000/ -> Boots up my homepage without SSL support. So anything CORS fails. Once I try and click on a subdomain. It's a big fail.

Today I went a bit further. Curious if anyone can see something blatantly incorrect about my approach here..

Started also forwarding ip6

sudo sysctl -w net.inet6.ip6.forwarding=1
net.inet6.ip6.forwarding: 0 -> 1

Created a new forwarding rule

sudo touch /private/etc/pf.anchors/org.user.forwarding

With

rdr pass on lo0 inet proto tcp from any to any port 80 -> 127.0.0.1 port 9000
rdr pass on en0 inet proto tcp from any to any port 80 -> 127.0.0.1 port 9000
rdr pass on en1 inet proto tcp from any to any port 80 -> 127.0.0.1 port 9000

Added it to /private/etc/pf.conf

Parse tested it sudo pfctl -vnf /etc/pf.anchors/org.user.forwarding . It was correct.

Rebooted, and ran sudo pfctl -f /etc/pf.conf; sudo pfctl -e .

Still need to include the port 9000 to access domain.

Could it be caused by https://github.com/code-mancers/invoker/issues/184?

[gotoAndBliss]

@WojtekKruszewski Thanks so much for the recommendation. I was previously on 2.1.5, and went to 2.3.0, but the problem still persisted.

I have bumped into the same issue. I can access my app fine by visiting localhost:9000, but if I visit web.dev I'm greeted by the usual

Application not running Invoker did not get any response. Please check if the application is running.

I'm using the latest version (1.5.4) and these are my configuration files:

$ cat /etc/resolver/dev
nameserver 127.0.0.1
port 23400

$ cat ~/.invoker/config
---
:http_port: 23403
:https_port: 23404
:tld: dev
:dns_port: 23400

$ cat /Library/LaunchDaemons/com.codemancers.invoker.firewall.plist

@Arkham Does this work for you: https://github.com/code-mancers/invoker/issues/194#issuecomment-316599726 ( It did for me, but didn't for @gotoAndBliss )

[Arkham]

Hey @swanandp! I've tried every suggestion in the thread and the current situation is:

• localhost:9000 ✅
• web.dev 🔴 Invoker did not get any response. Please check if the application is running.
• web.dev:9000 🔴 This site can’t be reached web.dev refused to connect.

@Arkham I had the same and was resolved by running with binding 0.0.0.0 (e.g. rails s -b 0.0.0.0)

[Arkham]

@Dan2552 amazing, works for me too!

[gotoAndBliss]

Would there be something similar for running rails thin?

[gnufied]

thin also has a -a option that you can use to specifying binding address.

[gotoAndBliss]

@gnufied Ah ok, because I tried -a 0.0.0.0, but nothing happened. Should the address always be 0.0.0.0?

[gotoAndBliss]

Purchased a brand new macbook, fresh install. Same issue. 😭

[gotoAndBliss]

I discovered that if I greenfielded a new app, everything works as expected. No port required.

I tried stripping down the problem app to practically nothing ( still in the process of stripping ). And everytime I make the call I get this error

whisper : 4736210368:error:1408F09C:SSL routines:ssl3_get_record:http request:ssl/record/ssl3_record.c:322:

Not sure if that means anything to anyone on this thread.
