I believe the 502 is caused by this:
!!! ERROR: main box container not found!
a.fn.init [selector: ".WooZone-country-check:first", prevObject: n.fn.init(1), context: document]
context: document

prevObject: n.fn.init [document, context: document, selector: ""]
selector: ".WooZone-country-check:first"
__proto__: Object(0)
