SSL certificate fails to be renewed

[lucasff]

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
Stack trace:

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.

@lucasff Did you find out how to solve the problem? I have now the same problem but I have no idea how to solve it. I can't even turn off the SSL. :(
