If you are using WooCommerce to deliver downloadable content and the links in the notification mails fail, try changing the download method as a possible solution.
Go to /wp-admin/admin.php?page=wc-settings&tab=products§ion=downloadable aka WooCommerce >> Settings >> Products >>Downloadable Products and change the download method.
Do a test run with each available setting.

My S3 download goes to an XML file?

Thanks for your message. If you have exhausted the options described in this post, I encourage you to continue with a conflict test or open a support ticket at WooCommerce.com.
Thanks. That resolved the problem for me.
Cheers. Glad to know it worked for you.
