I have defined a Functional test as follows:
$I = new FunctionalTester($scenario);
This generates the error:
[GuzzleHttp\Exception\ConnectException] cURL error 28: See http://curl.haxx.se/libcurl/c/libcurl-errors.html
Error 28 is:
Operation timeout. The specified time-out period was reached according to the conditions.
I'm really not sure where to start with debugging this?
