Hello,
I am using the following nginx.conf https://gist.github.com/nkhine/f620f8bdc0fb613b7b59 and have an EV Multi-Domain certificate from COMODO for my company.
This works on Chrome and Firefox, but I am having difficulties on Safari and Opera.

My server is FreeBSD 10 with ZFS, with Nginx running inside a jailed environment.

Nginx is used as a front end to a Node.js application.

There two issues that happen, on Safari, if i try to login using federated login, i get 'Too many redirects occurred' and on Opera i get 'Secure connection: fatal error (40) from server.'

Any advise much appreciated
