Site Key Does not working

This thread is resolved. Here is a description of the problem and solution.

Problem:
You are experiencing issues where the WPML plugin cannot connect to wpml.org, and you receive messages like 'Unable to parse data from service response' when entering a new site key from WooCommerce. This suggests a problem with the connection or the site key itself.
Solution:
First, ensure that your server's firewall settings are not blocking the necessary WPML domains. You need to allow the following domains:

wpml.org
cdn.wpml.org
api.wpml.org
api.toolset.com
cloudfront.net

If the issue persists, it might be caused by another plugin interfering with the WPML plugin. We recommend deactivating other plugins temporarily to see if the issue resolves. For more detailed guidance, visit WPML connection issues documentation.

If these steps do not resolve your issue, or if the solution seems outdated or irrelevant to your specific case, please open a new support ticket. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. For further assistance, you can contact us directly through our support forum.

yasserA-15	Background of the issue: I received a message saying 'WPML plugin cannot connect to wpml.org'. I previously connected successfully when I subscribed to WPML, but now it has disconnected. I tried to Connect it again with new site key but I received this message when i enter the new site key from woocommerce "Unable to parse data from service response." Symptoms: I received the message 'WPML plugin cannot connect to wpml.org' and 'Unable to parse data from service response' from WooCommerce. The site key is not working. Questions: Why is the WPML plugin unable to connect to wpml.org? Why is the site key not working? What does the 'Unable to parse data from service response' message mean?

yasserA-15	Our hosting provider can't whitelist domains but they can whitelist IP addresses. Can you provide us with these?

Andrey Supporter Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+02:00)	One of my colleagues will take on your ticket. In the meantime, I would like to provide some helpful information. We operate our services on Amazon servers, utilizing the AWS CloudFront CDN. Because the IP addresses of these servers can change continuously and vary based on the actual CDN delivery, the hostnames are only available. More information can be found here: https://wpml.org/faq/troubleshooting-registration/#wpml-plugin-cannot-connect-to-wpml-org

Andrey Supporter Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+02:00)	Here's the correct link: https://wpml.org/faq/wpml-plugin-cannot-connect-to-wpml-org/. I have checked our firewall logs, and we are not blocking your site. I suspect one of your plugins may be causing the issue or could be related to your server's firewall blocking the WPML API. The following domains need to be allowed if your hosting is blocking them. - wpml.org - cdn.wpml.org - api.wpml.org - api.toolset.com - cloudfront.net

yasserA-15	Our hosting provider can't whitelist domains but they can whitelist only IP addresses. Can you provide them please?

Andrey Supporter Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+02:00)	I have confirmed with our system team that we can only provide the domains to whitelist for the above reasons. I suggest contacting the hosting provider to explore whether there is an alternative way to whitelist or to ensure that the WPML API is not blocked in any other way.

yasserA-15	I already asked them but they say that they don't usually block any IP addresses then I looked in Cloudflare maybe it's blocked from there but they didn't block any IP's as well it's also the same system in Hostinger or Cloudflare they both want IP adresses not domain name so they can check So What can we do now?

Andrey Supporter Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+02:00)	Thank you for your feedback. Could you confirm that the same issue happens if only WPML plugins are enabled on the site?
March 20, 2025 at 4:17 pm #16841232
yasserA-15	Yes, I have tried disabling all the plugins and tested it, but it still didn’t work. I also changed the theme to the default one, but nothing changed. I have the latest version of WordPress and the latest version of the theme, with no available updates except for WPML, which I cannot update due to the inability to register.
