IMPORTANT NOTES:

  • The following errors were reported by the server:

    Domain: www.jardevs.com
    Type: connection
    Detail: Failed to connect to host for DVSNI challenge

    Detail: Failed to connect to host for DVSNI challenge

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you’re using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

Are you sure you want to use the --apache plugin? Your domain currently shows a nginx welcome page.

The webroot plugin might work better for you if you’re using nginx.

Also, worth mentioning that the apache plugin works on port 443, so make sure you’re not blocking external access to that port in your firewall.
