To start with, I’d suggest visiting the URI in the log for more information. It is not the most user friendly to look at, but there is lots of helpful data available.
“Visit the following URI for more information: https://acme-v01.api.letsencrypt.org/acme/authz-v3/479791894”
Once you visit the URI you can see the status is invalid. Looking at the detail you can see the URI that LetsEncrypt is attempting to connect to in order to complete the HTTP challenge, http://mail.mani.pt/.well-known/acme-challenge/ekifo-LpC9IN5PDEZlDmxmUqtiUABDTDrh5r8BL8iJM You can also see that it is getting a 400 connection refused error. Looking further down in the information you can see that LetsEncrypt resolved mail.mani.pt to 195.22.7.222.

},
When I attempt to open the URI provided in the details with a browser I also get ERR_CONNECTION_REFUSED. So for some reason, it looks like your web server is rejecting the connections.
