HTTP/2 returning weird symbols

  • 772

So I switched my nginx server over to use HTTP/2, and it works for Edge and Chrome. On IE11 however I'm getting no response, only this:

On firefox the page simply refuses to redirect or load, not even an error message.

My SSL settings look like this:

ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH;
ssl_prefer_server_ciphers on;

What would be causing an issue like this, as I'm confused why it's working in Edge and Chrome but nowhere else?

Also, when downloading files, I get corrupted ZIPs and BZ2s which is making it even more confusing.

Nginx version is 1.9.7 if that helps.

I have downgraded to 1.8.0 in the meantime. :(

  1. I believe HTTP/2 only works over TLS1.2. Try taking out 1.0 and 1.1. Also remove the caching for diagnosis. Here's my working HTTP/2 configuration with a Let's Encrypt certificate. HTTP/2 support is still relatively new, suggest upgrading to the latest nginx, currently 1.9.9.

    ssl_certificate /path/to/fullchain.pem;
ssl_certificate_key /path/to/privkey.pem;
ssl_protocols TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:!ADH:!AECDH:!MD5;

    This may not solve your problem but it's will at least give some information that will help diagnosis.
