I’ve already found the solution.  As I use ‘s3’ and ‘CORS’, so I edit this file:-
vendor/fineuploader/php-s3-server/endpoint-cors.php
At line 283, change from
	$link = getTempLink($bucket, $key);
	$response = array(“tempLink” => $link);
to
	$link = getTempLink($bucket, $key);
	$link = str_replace( “{$bucket}/”, “”, $link );
	$link = str_replace( “s3.amazonaws.com”, “{$bucket}.s3.amazonaws.com”, $link );
	$response = array(“tempLink” => $link);
The same may apply to vendor/fineuploader/php-s3-server/endpoint.php line 257.
