VestaCP SSL certificate installation

First, go to the WEB tab 

Then you need to click the "SSL support"

• If the certificate was not purchased in advance, then you can simply click the "Let's Encrypt Support" checkbox.  In this case, a free certificate will be automatically generated, which will then be automatically renewed. 

• If a paid certificate was purchased in advance, then you just need to enter the text content of the certificate / key files and (if present) intermediate certificates in the appropriate fields.
