SSL certificate fails to be renewed

```
Debug: Loading account keypair (33.751s)
Debug: Starting check with solver http (33.751s)
Debug: Loading the authorization token for domains [REDACTED], www.[REDACTED] ... (33.752s)
Debug: Challenge loaded. (33.752s)
Debug: Testing the challenge for domain [REDACTED] (36.953s)
```

Then in this step, it gets stuck for a long time.

Finally, I get a PHP Fatal:

```
PHP Fatal error: Uncaught Exception: Can not validate challenge for domain [REDACTED] in phar:///usr/local/bin/ee/vendor/easyengine/site-command/src/helper/Site_Letsencrypt.php:387

```

What I'm noticing is that while the command is running, the website goes completely down. I think the proxy container is not behaving well, so the LE challenge doesn't complete properly.

Inizia da vendor/easyengine/site-command/src/helper/Site_Letsencrypt.php alla riga 387 e dal flusso SSL in class-ee-site.php intorno alle righe 1303–1536. Riproduci il comando di rinnovo con le versioni segnalate di Docker e Docker Compose, quindi traccia il controllo della challenge HTTP e il comportamento del container proxy. Il lavoro è completato quando la challenge viene convalidata e il sito web rimane disponibile durante il rinnovo.
