Sync not working

Hi,

I tried sync my 140 products, but only 15 synced.

I’ve checked the wp-feed-upload log file, and it comes up with these errors:

2021-05-25T13:34:54+00:00 DEBUG Batch Response:
2021-05-25T13:34:54+00:00 DEBUG WP_Error Object
(
    [errors] => Array
        (
            [http_request_failed] => Array
                (
                    [0] => cURL error 28: Operation timed out after 5000 milliseconds with 0 out of -1 bytes received
                )

        )

    [error_data] => Array
        (
        )

    [additional_data:protected] => Array

How do I proceed from here and secure all my products will sync?
