Is this a new installation? If so, please verify that the API URL and Key are correct and try again.
If you know the API URL and Key are correct, check with your web host to ensure that they are not blocking communications from the ActiveCampaign server.
It could be an issue with the ActiveCampaign’s servers.
It may be possible that the connection is timing out before an error response is returned to your website
The following code would extend the timeout duration. Can you add the following code to your theme’s functions.php file?
<?php
/**
* Extend http timeout duration to 60 seconds as per ActiveCampaign
*
* @param int $timeout The timeout duration in seconds. Default is 5.
*
* @return int The filtered timeout duration in seconds.
*/
function __extend_http_request_timeout( $timeout ) {
return 60; // seconds
}
add_filter( 'http_request_timeout', '__extend_http_request_timeout' );
