On 5 pages on our site we've got an Error Code 803: Incomplete HTTP Response Received. We checked the network interface within the browser inspector, which did not return any errors, this would mean than there were no issues with retrieving resources from the server. In the console log there are no errors also. We also inspected the URL bar settings and can see each page is loaded under a secure connection with no errors. When using http://www.webconfs.com/http-header-check.php there was a "HTTP/1.1 301 Moved Permanently" issue. A little in the dark on what to do next. Any help would be amazing!
