I have set up the pull zone for a site and installed the plugin. I have waited over an hour and the test link still fives 400 Bad Request page. The test link is https://bf5xhtwrkszz.cdn.shift8web.com/wp-content/plugins/shift8-cdn/test/test.png. I fI paste that URL directly into a browser I get a 502 Bad Gateway page.
I tried exactly the same steps with a local copy of the site and it works fine - the test link and also when I make everything active. The hosting company for the site that doesn’t work say there is nothing wrong at their end.
Any thoughts, please?
