your connection is not secure

when i go to admin page i get this error “SSL_ERROR_BAD_CERT_DOMAIN” and your connection is not secure,how can i solve this problem?thank you!

Which admin page are you referring to? The admin page on your own website? That’s because your admin area apparently forces HTTPS on all connections. We enable HTTPS for all websites by default, however we cannot create valid SSL certificates ourselves. To fix that, you will need to get an SSL certificate for your domain.
