I am trying to charge a card through the sandbox. The only error that I get is a 503 error in the browser console:
Failed to load resource: the server responded with a status of 503 () /checkout/wc-ajax=checkout
I am working on a staging copy of the site. The site is publicly available. I am using TLS 1.2.
I am only getting a blank error on the page.
I'm not sure how I would further troubleshoot this issue. Please advise.
