How to install SSL on Nginx + Apache bundle?

Question

Nginx

Hello. Here's the problem. I took the free Comodo. Installed as it should through VestaCP admin panel accepted everything, etc. Vesta has created separate configs for nginx and apache with the ssl appendix.
sitenam.nginx.ssl.conf
sitenam.httpd.ssl.conf
Everything is cool, but at the same time, when I try to access https://example.com , I get a response from Chrome

This site cannot provide a secure connection
The sitename site sent an invalid response.

Broke through the Internet. I checked the config and everything seems to be correct. Where to dig I do not know any more. Tell me what could be the problem?
PS Let registered before certificates. Apache rotates these ports 8080 and 8443 and passes them to Nginx, as I understand it. In configs everywhere the certificate is specified but nothing works. over HTTP everything works fine. Thank you in advance .
