Netlify dev not starting at 8888

Hello netlify fam,

I’m working to migrate functions to netlify vs. another microservice backend, and part of that is getting a netlify dev workflow going.

Unfortunately, I can’t seem to get the netlify dev server up and running.

Node v14.18.1 (so it’s not the node v17 issue)
Netlify-cli up to date (v8.6.0)

I’ve tried manually specifying the framework (CRA), and using -targetPort 3000 but neither have made a difference.

No matter what I do, I don’t get the magic box saying

   │   ◈ Server now ready on http://localhost:8888   │

Output from netlify dev command:

$ netlify dev --debug                                                                                                                                                                                                                                          [10:05:34]

Starting the development server...

Compiled successfully!

You can now view [redacted] in the browser.

  Local:            https://localhost:3000
  On Your Network:  https://[redacted]:3000

Note that the development build is not optimized.
To create a production build, use yarn build.

And that’s it… I never get anything else.

Worth noting: hitting localhost:8888 doesn’t do anything, no response.

Update:

I’ve identified the issue: CRA is configured to use HTTPS/SSL, but I can’t seem to get netlify dev config’d to do the same, despite following the instructions here:

Update2:

Disabling CRA HTTPS

#.env
HTTPS=false

and configuring netlify.toml as per the documentation:

[dev]
  [dev.https]
    certFile = "ca.pem"
    keyFile = "ca.key"

Now correctly starts up an https server on localhost:8888 when running netlify dev

TL;DR:
Ensure your app is running via HTTP, configure netlify to serve HTTPS, otherwise netlify dev will silently fail.

Notes for netlify:
Would be nice to have some sort of error handling for this if SSL is not in the expected state.
