Lets Encrypt HTTPS Not Working in Chrome and Firefox

I’m running latest EE (3.4.1) mainline on Ubuntu 12.04 LTS 64 bit.

I enable SSL with:

ee site update example.com --letsencrypt

When I open site in Chrome I see this message below and nothing else:

ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY

In Firefox the page is completely blank.

In IE 11 site works fine.

Any ideas what’s going on?

could you paste your server configuration here? (your domainname.com file in /etc/nginx/sites-available/)

I am also facing same problem… :confused:
