I have enabled TLS1.3 on three servers that are behind another load balance server that has itself TLS1.3 enabled. I get different results if the domain name is written without www. All servers have active ssl certificates. Here are the test results when testing in cdn77 checker:
I get "Excellent" if www.waylisting.com is tested. However, I get "Poor" in Firefox and "Moderate" in Google Chrome if waylisting.com is tested without www.
I have no errors regarding ssl when testing in gmetrics, pingdom, and so on. What am I missing in my configuration
