# Node.js Connection Check
## What is this check for?
Make sure the built-in node.js has access to GitHub.com or GitHub Enterprise Server.
The runner carries its own copies of node.js executables under `<runner_root>/externals/node20/` and `<runner_root>/externals/node24/`.
All javascript base Actions will get executed by the built-in `node` at either `<runner_root>/externals/node20/` or `<runner_root>/externals/node24/` depending on the version specified in the action's metadata.
> Not the `node` from `$PATH`
## What is checked?
- Make HTTPS GET to https://api.github.com or https://myGHES.com/api/v3 using node.js, make sure it gets 200 response code.
## How to fix the issue?
### 1. Check the common network issue
> Please check the [network doc](./network.md)
### 2. SSL certificate related issue
If you are seeing `Https request failed due to SSL cert issue` in the log, it means the `node.js` can't connect to the GitHub server due to SSL handshake failure.
> Please check the [SSL cert doc](./sslcert.md)
## Still not working?
Contact GitHub customer service or log an issue at https://github.com/actions/runner if you think it's a runner issue.
