The Snapshots plugin won't proceed past my wp_post_meta

The Snapshots plugin won't proceed past my wp_post_meta table during a restore. It gets to 100% (tho doesn't complete the table) and won't budge. I increased the RAM allotment to PHP and Wordpress and significantly raised the PHP max execution time, and had no change in result.

I only saw an error message once, out of numerous tries. The error was:

Gateway Time-out

The gateway did not receive a timely response from the upstream server or application.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
Apache Server at clients.selfagency.co Port 80

After that error I increased the RAM and max execution time.

Here is a screenshot of where it craps out:
