SOLVED: cURL error 6: Could not resolve host: api.wordpress.org

[winstonford]

In Tools > Site Health

I get this msg:

Your site is unable to reach WordPress.org at 198.143.164.251, and returned the error: cURL error 6: Could not resolve host: api.wordpress.org

This solved it:

Docker Desktop > Preferences > Docker Engine:

I replaced

{
  "debug": true,
  "experimental": false
}

with

{
  "dns": ["8.8.8.8", "192.168.0.1"]
}

and clicked

Apply and Restart

then did:

docker-compose up -d

The setting lives here:
~/.docker/daemon.json

Codebase

Built-in vanilla WordPress

Host OS

macOS 12.1 Monterrey

Docker compose file

Make sure you remove all commented services.

# Content of your docker-compose.yml file. Make sure you remove all sensible information you might have there.

Logs output

# Run "docker-compose logs [service]". Let's say you get 500 error for some reason then it'll be helpful to provide logs for php and http server (nginx/apache) services.
