Hello, I am very new to all these things, and wanted to have ssl for my own server (Openbsd6.2, Openbsd httpd, Openbsd acme-client), which will be my first ssl, other than previous self-signed one.
Previously, to create a website, I followed some blog posts and created self-signed ssl (http://thecyberrecce.net/2017/01/15/secure-webservers-with-openbsd-6-0-setting-up-httpd-mariadb-and-php/), and as the site was somehow ready so I wanted to have the Letsencrypt ssl on the site, replacing the existing self-signed one. After reading man pages, documentations, and blog posts, (but I don't understand much really) I did just almost the same as others stated in their blogs (httpd.conf, acme-client.conf and then the command), using "acme-client -vvAD example.com" command. But I got an error ("provided agreement URL doesn't match" or similar), and then tried several times again while making changes (e.g deleting self-signed crt, etc...) but I still get an error: "no registration exists matching provided key". Could anyone help me know what the error means or give any advice to me? Also this is my second time writing to a "mailing list", and at the first time I couln't send a reply to say thank you to the reply that sent to me as I don't know how to reply. So I'd be really grateful for kindly letting me know that as well. Would really appreciate any help.
