Describe the bug

When clicking the 'Next Page' button of an archived page in PyWB, a 502 Bad Gateway Response is received after triggering a POST request.

Steps to reproduce the bug

1 - Go to the URL: https://orcl.my.site.com/CLR_Search
2 - Scroll down til the 'Consultant Lobbyist' section
3 - Click the 'Next Page' button with the dev tools opened
