Fatal error on selfTest

[bessone]

Hello,

in my project (with Guzzle 7.9.2) selfTest fails when the domain is not configured on the dns.

In the selfHttpTest method the error is checked in a try catch block, but the exception caught is GuzzleHttp\Exception\RequestException

yaac/src/Client.php

Line 405 in fcb8417

protected function selfHttpTest(Authorization $authorization, $maxAttempts)

instead I get the exception GuzzleHttp\Exception\ConnectException

[object] (GuzzleHttp\\Exception\\ConnectException(code: 0): cURL error 6: Could not resolve host: domain.tld (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://domain.tld/.well-known/acme-challenge/tio8iBrKrML3qvNZsDnGvgmcrVXX-GpjxDH25Zfi3ZY

this causes an error to occur, unless I catch it in my code.

I don't know if Guzzle 7 returns a different exception than Guzzle 6, I thought about doing a PR to catch both exceptions, but the multiple catch is only present from PHP > 7.1 and this project does not have a limitation on the PHP version, so for those who still use PHP < 7.1 it would become incompatible.

Thoughts?
