When REQUEST LET’S ENCRYPT CERTIFICATE button is clicked, this server is tested by Let’s Encrypt to ensure that you have the rights to get a certificate. The necessary conditions are:
_ The server must be reachable from outside at port 80. Make sure your port 80 is open to the public Internet (you can check with sites like http://www.canyouseeme.org/)_
_ The domains that you want the certificate for, must be public domain names associated to server’s own public IP. Make sure you have public DNS name pointing to your server (you can check with sites like http://viewdns.info/)_
Thank you all,
at this point I would like to know what you recommend, WebTop 4, WebTop 5 or SoGO?
my is a simple installation where I would like to integrate nextcloud with groupware, but not indispensable!
