HTTP/2 and Browsers

So I recently switched a website to HTTP/2, however the SSLLabs is saying this error about FireFox and Safari, amongst other:

Server negotiated HTTP/2 with blacklisted suite
RSA 2048 (SHA256)   |  TLS 1.2 > h2    |  TLS_DHE_RSA_WITH_AES_128_CBC_SHA  |  DH 2048 

When loading the website with FireFox, I get no error, no response, nothing.

 

What doesn't make sense is that my SSL settings in NGINX seems fine!

 

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ecdh_curve prime256v1;
ssl_session_tickets off;
ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS';
ssl_prefer_server_ciphers on;

What exactly am I doing wrong? I cannot figure this out for the life of me
