devtools-integration error in version v10

[smoky dome]

If I put "http :false" everything works ok

this is my nest info

mini repo: https://stackblitz.com/edit/nestjs-typescript-starter-bmuyup?file=src%2Fapp.module.ts

Which OS are you on?

[smoky dome]

I have problems at MacOS and Linux

ubuntu 22.04

[serene wigeon]

does it happen every time? What if you first kill whatever is running on that port? sudo kill -9 $(sudo lsof -t -i:4000)

[smoky dome]

Yes, i check it

every time

[serene wigeon]

I'm pretty sure you have to use a different port for the devtool module and for the app's webserver itself

when do

await app.listen(3000);

and

DevtoolsModule.registerAsync({
      useFactory: () => ({
        http: true,
        port: 4000,
      }),
    }),

Then it boots up correctly

[smoky dome]

I will try it now

The app works, but I can't connect to devtool

I have problems at MacOS and Linux, but Window work

[muted isle]

how your devtoolsmodule setup looks like now?

[serene wigeon]

but I can't connect to devtool
How are you connecting?

[smoky dome]

On windows devtool and app sharing port 4000, it works fine.
But not mac and linux

i try 4000, 3000, and replace localhost to 127.0.0.1

[muted isle]

it's working here on Ubuntu

can you make a reproduction to share with us?

[smoky dome]

i can share vps ubuntu, i pm u

[muted isle]

oh so it might be networking issues right

[serene wigeon]

working for me as well

[smoky dome]

Network problem? I'm not sure

[serene wigeon]

btw it won't work if you're trying to connect to stackblitz

[smoky dome]

i try to connect with ipv4

[muted isle]

Are you doing everything in the same machine or it is a remote access?

[smoky dome]

i try on local window and deploy to vps

My colleague tried it on MacOS and it didn't work

[serene wigeon]

and are you trying to connect to the IP of the VPS?

i try 4000, 3000, and replace localhost to 127.0.0.1
127.0.0.1 is still localhost

[smoky dome]

I tried with ipv4 of vps

[serene wigeon]

if they use port 3000, do they see the "hello world" message?

[smoky dome]

Yes. everything is working properly except devtool

[serene wigeon]

just to confirm - when it's deployed on the VPS, then nobody can connect to the devtool from any machine

[smoky dome]

Yes

And MacOs, ubuntu share the same port causing error

[serene wigeon]

the log shows you're running the server on port 4000, not the devtool module

[smoky dome]

I tried 4000 and 5000

[serene wigeon]

that error in the console is still the old one. What does the devtools window say when you try port 5000?

[smoky dome]

Nothing happens

[serene wigeon]

Not even this error?

[serene wigeon]

I was able to connect to the devtool module even when the project runs in a docker container

I truly have no idea what could be wrong at your end

[smoky dome]

i share u vps

There is a problem with the network
and when using common port for application and devtool on Mac and Ubuntu

[muted isle]

the question is: do we must use different ports? I’d say yes. The docs doesn’t mention that so we should improve it and see what Kamil think
