cURL error 28: Failed to connect to cdn.wpml.org port 80 after 10001 ms: Timeout was reached

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

Problem:
If you're experiencing repeated cURL error 28 messages indicating a failure to connect to cdn.wpml.org after a timeout, this might be due to a routing issue on your side or a need to whitelist WPML servers.

Christopher Amirian WPML Supporter since 07/2020 Languages: English (English ) Timezone: Asia/Yerevan (GMT+04:00)	Hi, Welcome to WPML support. I checked with our system support, and all the systems are running with no issues. I also checked, and hidden link is not blocked on our side. This means you will need to check and whitelist our servers as mentioned by the AI chat assistant. There is nothing that we can do on our side here. For more information: https://wpml.org/faq/wpml-plugin-cannot-connect-to-wpml-org/ Thanks.
