Resolved SSL Error

[nate]

Hi,

I'm using the Let's Encrypt extension and on older browsers receiving the error:
ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY

I've just managed to get it working using the following in nginx directives:
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
ssl_prefer_server_ciphers on;

Is this the best way to achieve this?

Thanks

According to the error message this is a SPDY issue, so the certificate and the cipher suites are not the cause.

As a temporary fix, you can apparently disable its support in your browser/registry/server.
