Hey,  
you need to change the ListenAddress in the Mattermost config according to the port specified in nginx (in your case 8065. Mattermost will listen on this port on localhost and nginx will proxy requests, which came in on 443, to 8065. With your configuration now nginx binds 443 and Mattermost tries to bind 443 too (ot the other way around).

Best regards,  
Marco
