Hi websitefun, I submitted the domain here:
It shows that none of their Firefox test systems could connect. I believe it is because the list of ciphers is too restricted. You can view the ciphers supported by Firefox if you visit the following page in Firefox:
So for example, the server supports:
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028) TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (0xc027)
Firefox doesn't support CBC in this configuration. Try adding these ciphers to your server configuration:
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030) TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f)
As a point of comparison, my web host went to TLS 1.2-only last year, and only supports four ciphers but shows the ability to connect to all of the test browsers:
Not sure how they chose those ciphers.
hi jscher200 - thanks for information I am working to get the ciphers added so I can test will let you know if problem is resolved
