I'm unable to send responses to an additional email, the responses will go to the email address on file in your wpml.org account.

Please try the following steps:
1. unregister your site from WPML and then register it again.
- Unregister: https://wpml.org/faq/install-wpml/#unregister
- Register: https://wpml.org/faq/install-wpml/#register

2.Check the Installer Log under WPML > Support to ensure the subscription was working correctly.

3. Go to Plugins -> Add New -> Commercial and click 'Check for Updates' to see if any messages appeared. Do you have any messages? If so, let us know.

4. Check with your hosting provider to ensure that specific IPs crucial for WPML's functionality are resolving correctly. I know they checked the URLs, but please also have them confirm the IPs. The IPs to check are:
d7j863fr5jhrr.cloudfront.net: 13.33.123.118
cdn.wpml.org: 52.85.213.119
api.wpml.org: 54.221.250.24
api.toolset.com: 34.193.222.18

If these are not resolving, your hosting provider may need to manually add these IPs to the /etc/hosts file.

5. COnfirm that your hosting provider has the WordPress REST API enabled.

Please let me know the results after following these steps.

3. Go to Plugins -> Add New -> Commercial and click 'Check for Updates' to see if any messages appeared. Do you have any messages? If so, let us know.

Connection error: Unable to get data from service. Detailed error: cURL error 28: Failed to connect to api.wpml.org port 443: Connection timed out

I added these IPs to our firewall and still not able to connect to your server

Please have your support team look into this to see why we are not able to resolve this ASAP! We can not wait. Thank you!
