Problem:
If you're experiencing issues connecting to the WPML API server and suspect that your server might be blocked or unable to establish a connection, it's important to verify several aspects to diagnose the connectivity problem.
Solution:
First, confirm that the IP address '192.169.179.165' is the correct public IP for your server and that it's configured to host your WordPress site. Check if there are any firewalls or security services like Cloudflare or ModSecurity that could be blocking outbound connections.
Next, connect to your server via SSH or your hosting control panel's terminal and execute the following commands to gather more information about your server environment and network settings:
nc -vz -w 10 api.wpml.org 443
curl -I https://api.wpml.org --max-time 10
getsebool -a | grep httpd_can_network_connect
These commands will help determine the operating system details, DNS resolution for api.wpml.org, connectivity to api.wpml.org on port 443, HTTP response from api.wpml.org, SELinux status, and whether Apache or PHP-FPM can make outbound connections.
If the issue persists, check if the outbound firewall or network policy is blocking port 443 and consult with your hosting provider to enable SELinux and the 'httpd_can_network_connect' boolean. This will allow outbound connections necessary for WPML.
If these steps do not resolve the issue, it might be due to server-level configurations or restrictions beyond our control. In such cases, we recommend contacting your system administrator or hosting provider for a detailed investigation.
