Good afternoon

UCC ssl the certificate is bought from godaddy for 5 domain names.

One of the sites (settles down on the separate server) doesn't open from safari "Safari can't open the page https://sendy .mysite.com because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then TR again." In too time it normally opens from all other browsers.

Debug log of nginx (nginx 1.8.0, ubuntu 14.04):

}

All other sites / domains are located on another server with the same certificate ucc, and they open in Safari without any problems

What is the cause of the problem?
