The error: wpml: cURL error 7: Failed to connect to api.wpml.org port 443: Bad access Meaning: WPML is blocked by a firewall Solution: Contact your hosting provider and ask them to whitelist the following domains: wpml.org cdn.wpml.org api.wpml.org api.toolset.com cloudfront.net If this will not solve the issue, please let us know. Best regards Andreas

larryP-3	Hello, it appears that whitelisting has not resolved the issue I still get the following: Connection error: Unable to get data from service. Detailed error: cURL error 7: Failed to connect to api.wpml.org port 443: Connection timed out I also tried hardcoding the serial number in the WP-Config.php file and this did not work either. I got a message indicating it should be removed Please can you offer advice on how to install this. Note that this is a multisite environment with subdomains. I have tried installing the plugin activated on the network and also activated on the main site which is hidden link Regards Alan

Otto WPML Supporter since 09/2015 Languages: English (English ) Spanish (Español ) Timezone: America/Argentina/Buenos_Aires (GMT-03:00)	Hello Alan, Can you confirm that the server can reach api.wpml.org? If you have access to the server's terminal you can try this: curl -I <em><u>hidden link</u></em> As you use a multisite, please review the installation steps provided here: https://wpml.org/documentation/support/multisite-support/#install-wpml-multisite To ensure the quickest and most accurate support, please provide your debug information so I can look at some of your configurations. We have an excellent article on how to locate it here: https://wpml.org/faq/provide-debug-information-faster-support/. Best Regards, Otto
