HTTP2 site does not loads on firefox

Server NGINX
1

Hi,
We have recently deployed a site on http2 (with ALPN support) using
nginx.
The site does not open in Firefox 47.
The site supports following ciphers :

Protocols TLS 1.2 Yes TLS 1.1 Yes TLS 1.0 Yes SSL 3 No SSL 2 No

Cipher Suites (SSL 3+ suites in server-preferred order; deprecated and
SSL
2 suites at the end) TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)
ECDH
secp256r1 (eq. 3072 bits RSA) FS 256
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028) ECDH secp256r1 (eq.
3072

You need to provide more information such as Firefox error messages,
nginx
config, server hostname, etc. You may find
Network Monitor — Firefox Source Docs documentation useful.

I did notice your cipher suites include blacklisted ciphers, but this
shouldn’t be an issue for outright failure.
