Can't make wait-on work in Github action

[alexbjorlig]

Hi Jeff.

Thanks for an awesome library, but I can't get it to work on Github actions.

I use this command:

npm run start:test & ./node_modules/.bin/wait-on http://localhost:3000 --timeout 120000 -v

I can tell from the output that the server is up and running on port 3000, but wait-on only prints this output:

2021-01-03 11:42:52 info: Express is 👂  on port 3000/graphql. (Pid 2995)

When I test it locally it works perfect?

but I can access it from browser. Also tcp succeeds

That's very strange, I'll see if I can figure anything out with this. I appreciate you mentioning it.

Has anyone found any solution for this? I'm having the exact same problem and something strange is happening: it seems to work with 4.0.0 release, but not with 6.0.0.

If you're using cypress, this sounds interesting: https://github.com/bahmutov/start-server-and-test/issues/287#issuecomment-955592294

also having the same issue here, unable to wait-on the start in github actions. Maybe an issue with the github ci?

For me this was related to ipv6. It also happens with other HTTP request node libraries. Node.js seems to resolve localhost:3000 to ::1:3001, but my server was running on ipv4 only. Solved by using 127.0.0.1:3000 instead of localhost:3000

In my case, I wanted to run electron with a React App, then the script on package.js was "electron": "wait-on tcp:3000 && electron ." change for "electron": "wait-on http://127.0.0.1:3000 && electron ." fix the issue.

Some people are having better luck in GitHub Actions with the IP 172.17.0.1

There is also related info in: https://github.com/cypress-io/github-action/issues/802

For anyone having issues with Node 18 runners on GitHub Actions, try with Node 20 that has different defaults. At the same time GHA's IPv6 hosts/localhost configuration used to be quite specific, so you may end up having to use ip6-localhost to wait-on unambiguously even for ipv6-binding server.
