Which platform(s) does your issue occur on?

iOS, MacOS Sierra, 10.12.6

Please provide the following version numbers that your issue occurs with:

• CLI: 3.1.1
• Cross-platform modules: 3.1.1
• Runtime(s): "tns-ios":3.1.0
• Plugin(s): (look for the version number in the package.json file of your
  project)
  "nativescript-bottombar": "^3.0.4",
  "nativescript-geolocation": "^3.0.0",
  "nativescript-google-maps-sdk": "^2.3.2",
  "nativescript-ngx-fonticon": "^2.2.1",
  "nativescript-oauth": "^2.0.1",
  "nativescript-telerik-ui": "^3.0.1",

Please tell us how to recreate the issue in as much detail as possible.

1. Run: tns debug ios --chrome --emulator
2. Attempt to attach chrome debugger with resultant chrome-devtools url

Is there code involved? Not really. I think I can reproduce this with hello world.

When I issue the 'tns debug ios --chrome --emulator' command, everything starts up fine. When I attach the chrome debugger using the 'chrome-devtools' url that the command prints to console, chrome immediately shows a message saying it is disconnected and the console where I issued the command shows:
.
Frontend client connected.
Backend socket created.
Error: connect ECONNREFUSED 127.0.0.1:18181

at exports._exceptionWithHostPort (util.js:1073:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1093:14)

Chrome shows message popup:

"Debugging connection was closed. Reason: websocket_closed
Reconnect when ready by reopening DevTools"

Hi @wpfeiffe

Is it only applicable when you debug with chrome, or you can also reproduce with iOS Inspector?
Do you reproduce it each time when you run the command or only sometimes?

[wpfeiffe]

I can reproduce the issue every time with "tns debug ios --chrome". If I just issue "tns debug ios", the nativescript debugger starts and all is good for the length of the debug session. I am not sure what the "IOS Inspector" is. Is this another debugging tool? I'm somewhat new to mobile/nativescript so I haven't encountered that yet..

Hi @wpfeiffe

Thanks for the information.
"iOS Inspector" is what you get when you run tns debug ios.
I can not reproduce the issue at the moment, so I suppose it is environment related.

What are versions of node and npm on your machines?
Can you also check that port 18181 is not used by some other program or it is not blocked by something.

I have no idea if it will help or not, but I can also suggest reinstalling your Chrome browser.

[wpfeiffe]

It looks like port 18181 is open on my machine. I could try reinstalling chrome, but I actually see the same issue when I run from Intellij Idea nativescript plugin. I actually started attempting debugging in Intellij Idea, got/reported the same error to the plugin author. He asked if it worked in chrome. When I saw the result, I reported it here. So it appears the issue shows itself on 2 different debuggers. I agree its likely something in my environment, but having a hard time pinning it down. Thanks for assistance.

[wpfeiffe]

Node and npm versions
$ node --version
v7.10.0
$ npm --version
4.2.0

[dtopuzov]

I've tested with both node8 and node6, but never tried node7.

Hi @wpfeiffe do you still experience the issue with latest releases of {N}?

[wpfeiffe]

Not yet but I will update and retry...

[mkarthik415]

I have deleted folders and restarted the debug, then I got it to work
1.platform
2.hook

Also, restart your chrome.

Got the same issue since a long time as well. Running on node 6.0.0

[jujupec]

on your terminal
cache clean --force

And delete your cache in chrome

If you still reproduce the issue can you please post version of nativescript, node and package.json of your apps.
