Issues after Update

Hello,

We updated to the latest versions of WooCommerce and Stripe and now we are getting these errors intermittently:

Remote Post: wp_remote_post() failed. PayPal IPN won’t work with your server. Contact your hosting provider. Error: cURL error 28: Connection timed out after 10000 milliseconds
Remote Get: wp_remote_get() failed. The WooCommerce plugin updater won’t work with your server. Contact your hosting provider. Error: cURL error 28: Connection timed out after 5000 milliseconds

No changes were made on the server end. The errors are coming and going.
