# Could not resolve host

> Xcode couldn't download WebDriverAgent because this Mac has no internet. Check the connection and build again.

You see this: `xcodebuild` prints `Could not resolve host` while it fetches WebDriverAgent's source. Mobster shows `Mobster couldn't download WebDriverAgent. Check your internet connection and build again.`

## Why it happens

The first build downloads WebDriverAgent. This Mac couldn't reach the server, so nothing was built.

## Fix

1. Check that this Mac is online and that nothing on your network blocks the download.
2. Build again from Mobster for Mac.

## Check it worked

The build starts compiling instead of stopping at the download.

Checked 26 Oct 2026 against Mobster 0.4.0. Back to [Troubleshooting](https://docs.mobster.dev/troubleshooting.md#iphone).
