cURL error 60: Peer certificate cannot be authenticated with given CA certificates

this is not duplicate, and kindly, don't mark it -ve or duplicate as I've found no solution anywhere.

I'm trying to upload files to S3 with Laravel's built in s3 driver, but getting the following error

S3Exception in WrappedHttpHandler.php line 159: Error executing "PutObject" on "http://ift.tt/1Y0q9eI"; AWS HTTP error: cURL error 60: Peer certificate cannot be authenticated with given CA certificates.

So is there anyway to disable SSL verification exception just before uploading data to S3

Here is code snippet

$uploadFile = $this->_getFileToUpload($file);
Storage::disk('s3')->put($file, $uploadFile);

I just want to disable exception before put statement.

Thanks.

PS

versions that I'm using are:
