On a WordPress website hosted on a CentOS server, I got the following error on the header of the website.
Warning: An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums. (WordPress could not establish a secure connection to WordPress.org. Please contact your server administrator.) in /var/www/html/wp-admin/includes/translation-install.php on line 68
On debugging the code, I found the code returned “CURL ERROR 7”. This happens when the curl connection is blocked. I was able to curl to the URL from the command line.
curl https://api.wordpress.org/translations/core/1.0/
To error is due to SELinux. To fix the error, run the command
setsebool -P httpd_can_network_connect on
Or disable SELinux.
