    Today and yesterday I have several notices from XENFORO like this

    Code:
    Zend_Http_Client_Adapter_Exception: ReCAPTCHA (No CAPTCHA) connection error: Unable to Connect to ssl://www.google.com:443. Error #0: php_network_getaddresses: getaddrinfo failed: System error - library/Zend/Http/Client/Adapter/Socket.php:235

    Should I update something at the vm software level?


    and I also have errors related to shell_exec
    Code:
    ErrorException: shell_exec() has been disabled for security reasons - library/phc/AttachmentPlus/Helper/Helper.php:457

    The latter is enabled by #fpmconfig ... is there anything else to do?

    Code (Text):
    ; catch_workers_output = yes
    php_admin_value[error_log] = /var/log/php-fpm/www-php.error.log
    php_admin_value[disable_functions] = shell_exec

    Nginx 1.15.x
    MariaDB 5.5/10.x
    comment out that line with semi-colon in front
    Code (Text):
    ;php_admin_value[disable_functions] = shell_exec
    

    restart nginx + php-fpm
    Code (Text):
    nprestart
    


    network connectivity issues Xenforo - OpenSSL & XenForo 1.5 Issues maybe IPv6 related

    Are you using IPv6 on your server, if so ensure IPv6 is working

    IPv4
    Code (Text):
    ping -c4 www.google.com
    

    IPv6
    Code (Text):
    ping6 -c4 www.google.com

    Hi, I do not use ipv6 on this vhost yet.

    that line in the conf of php is already like that.

    Code:
    php_admin_value [disable_functions] = shell_exec

    Code:
    ping -c4 www.google.com

    that line disabled shell_exec, commenting it out re-enables shell_exec which your web app needs
