title: AWS Cloudfront 504 when POST update with Wordpress
body: <p>Cloudflare gives a 504 when we update our products on the wordpress backend, It works fine for Mutli-language pages but english (root) gives a 504 pretty much every time. The 1 time i got it to update it gave a 302. </p>
  
  <p>We go CF - ALB to EC2 server. All HTTPS and port 443.
  Example error:

  <p>Everything worked well with CloudFlare since we moved CloudFront we have had this error. </p>
