Thumbnail Generation Error - Failed to Retrieve | RSS Retriever | CyberSEO support forum

This is not a plugin issue. The log clearly shows a connection timeout on your server side:

First, CyberSEO Pro tries to download the image via cURL. Then, it automatically falls back to file_get_contents(). Both methods fail. This clearly indicates that your server cannot reach automatadr.com; it does not mean that the plugin is doing something wrong.

The image itself is accessible, and downloads without any problems in other environments (tested). Therefore, the issue is either:

• a network/firewall restriction on your server or
• the remote server is blocking your server's IP address.

In short, this is a server-to-server connection issue. Please contact your hosting provider to investigate outbound HTTPS connections from your server.
