Action fails with connection errors (`ETIMEDOUT`, `ENETUNREACH`)

I keep hitting this:

```

```

any idea why?

I just have:

```
- uses: gradle/actions/wrapper-validation@v3
```

in my config so nothing special afaik.

Start with the linked GitHub Actions run and the workflow step using gradle/actions/wrapper-validation@v3. Compare the ETIMEDOUT and ENETUNREACH failures with the action's documented network requirements and determine whether the issue is reproducible. Done means identifying an actionable cause or documenting that it is runner- or network-specific.

Written by the indexing model from the issue text.
