Symptom: Command ‘ionic serve’ fails on AWS EC2 instance with RHEL 8. The browser says the connection is refused.
-
Message:
> ng run app:serve --host=localhost --port=8100
[ng] ℹ ｢wds｣: Project is running at http://localhost:8100/webpack-dev-server/
[ng] ℹ ｢wds｣: webpack output is served from /
[ng] ℹ ｢wds｣: 404s will fallback to //index.html
Additionally, the same message comes out when I successfully ran the same command on Win 10; but there were some more like below:
[ng] chunk {common} common.js, common.js.map (common) 22.9 kB [rendered]
[ng] chunk {core-js-js} core-js-js.js, core-js-js.js.map (core-js-js) 77.9 kB [rendered]
