Twitter SSL handshake error on Forge server with Lets Encrypt SSL

Hi, my website is running on Forge with SSL and https is valid in browser. I added FB, Twitter meta tag for having branded fb and twitter cards when sharing on these media.

Following :

     'ERROR: Fetching the page failed because other errors. '

is raised when trying to display twitter card in tweets (tested with https://cards-dev.twitter.com/validator )and this is linked, after research, to this dedicated wellknown issue :

https://twittercommunity.com/t/error-fetching-the-page-failed-because-ssl-handshake-error/30204/9.

It establishes that on Apache server serving different sites, a ServerName directive that matches the SSL certificate’s CN is needed to avoid Apache sending the local host name or the IP of the connection.

How to solve this twitter issue on NGINX server?Is it the same issue as Apache server?Does someone know what configuration changes are needed?
