Please share the entire output and also the answers to the following questionnaire, which you _should_ have gotten when starting a thread in the #help section: * * * Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. [crt.sh | example.com](https://crt.sh/?q=example.com)), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help. My domain is: I ran this command: It produced this output: My web server is (include version): The operating system my web server runs on is (include version): My hosting provider, if applicable, is: I can login to a root shell on my machine (yes or no, or I don't know): I'm using a control panel to manage my site (no, or provide the name and version of the control panel): The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you're using Certbot): * * * Further more, your website is unreachable at the moment. When using the `http-01` challenge, a working HTTP website on port 80 is required. ---

> [@Mrhawk](#): > > the site is reachable for cloud.falcopos.it with blank page is correct. I'm getting a time out. Other sites on the web confirm this: [https://downforeveryoneorjustme.com/cloud.falcopos.it](https://downforeveryoneorjustme.com/cloud.falcopos.it) A working HTTP website on port 80 is required when using the `http-01` challenge. Sometimes locally a site works, but internationally, it doesn't. Other examples showing the site being down: > **[Online of niet?
