Hi, I would like to fix bug in the nginx configuration. I created a merge request !1364 In the original code, this part of code `$output = $app->system->exec_safe('nginx -V 2>&1');` return the last line from the result of the command: `configure arguments: --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/l...` Correct information is in second or third line by distribution: `built with OpenSSL 1.1.1g....` But in "system" exist function `getopensslversion` that returns open ssl version from command `openssl version`. If the version from `openssl version` is not sufficient, than i can check all lines from `nginx -V 2>&1`. And second problem was in $vhost_data key `tls1.3_supported`, key cannot contain dot, as you can see in `tpl.inc.php` on line 327 /^[A-Za-z_]+[A-Za-z0-9_]*$/
