Live reload: EADDRINUSE: address already in use

[ArnaudDenoyelle]

Current Behavior

Just after creating a new nest project via nx :
Trying to save a file results in a EADDRINUSE error instead of live-reload
This happens only if the project is created with Nx. I can't reproduce it in a pure Nest repo

Expected Behavior

When I save a file, the server should live-reload

Github Repo

https://github.com/ArnaudDenoyelle/nest-EADDRINUSE

Steps to Reproduce

1. Create a project : npx create-nx-workspace@latest acme --preset=nest --appName=api --nxCloud=false
2. Go to the project directory : cd acme
3. Start the server : nx serve api
4. Modify a file like in app.service.ts and save

Additional Information

Can be fixed by downgrading @nrwl/* dependencies to 15.3.3, in particular @nrwl/nest and @nrwl/node alone

I'm facing the same problem with new installation. It is not just happening with nest, I even tried to install express and the issue exist even for express framework.

@AgentEnder - I forked this repository and reverted #13813, it solved the problem so looks like the problem is 2 weeks old. I have got the resolution, let me raise a PR in couple of hours.

[firxworx]

Confirmed in 15.4.1

[beeman]

Also seeing this issue, it's pretty inconvenient.

I tested #14023 locally and that fixes it, let's hope it ships fast!

[hallowatcher]

Same issue here on every save, I have to restart the whole process which is very inconvenient.

Nx 15.4.1

Faced the same issue when updated to 15.4.1 on every save.
Updated to 15.4.4 fixed it!

[pkyriakis]

Had the same issue, upgrating to the latest nx version fixed it!
