I used to generate the certificates with Let’s Encrypt CLI manually, but now the new ghost-cli production procedure does that for you.
After the procedure with ghost-cli is done, and the certificates are generated. I’m able to access my site from every browser apart from Google Chrome. From Chrome I keep getting a ERR_SSL_PROTOCOL_ERROR and this is something that is even happening to people that are accessing the site for the first time in different computers.
From Safari I’m able to access the site just fine.
