Let’s Encrypt is a free certification authority that provides free X.509 certificated for TLS encryption. An automated process enables to facilitate the creation, verification, setup, and renewal of SSL certificates for protected websites.
For more information, please refer to the official website.
Please note the following limits
More information about additional limits can be found here.
Before you add Let’s Encrypt certificate, make sure that the domain name leads to existing IP address of the control panel, as the system will verify that you are the owner of that domain.
A file with token and data for verification is created in
Let’s Encrypt sends a request by the domain name and reads the token.
After the certificate is issued, a new cron job is added. It will check if the certificate needs to be renewed:
0 0 * * * "/usr/local/mgr5/etc/scripts/acmesh"/acme.sh --cron --home "/usr/local/mgr5/etc/scripts/acmesh" > /dev/null
If several certificates for 3d-level (and higher) domain names are issued, you may face the "Too many subdomains" error. This Let’s Encrypt restriction allows to continue the issue procedure after a while (normally, within 24 hours).
Apache and Nginx web-servers are supported. If none of these servers are running, a built-in server will start to receive requests from Let’s Encrypt during domain verification.
When you add an existing certificate, domain name and its IP address are not checked. If domain and IP address do not match, the corresponding icon will be shown next to the certificate.
If OS supports Server Name Indication, you can add several SSL-certificates for different domain names. When you access a panel via domain name, the panel will use the certificate corresponding to that domain name.
Server Name Indication is supported by:
Certificates with alternative domain names are also supported.
