We have a custom domain with a wildcard SSL certificate configured, and a route created on our Java web app for it. Our DNS A record is configured to 5.10.124.142 as our app is running in London. However, requests are not reliably routed to our application. Some requests make it through, others return a 404 with error message "The application or context root for this request has not been found".

This is causing us major problems, can anyone help please?
