mobile search enterprise vault 11.0.1 fails to login.

Event log fills up with the below on every authentication attempt. Symantec support has been worse than useless (3 or so weeks before the guy even successful calls). 

very frustrating because the install is so basic on a proxy server, the only thing you can specify is your EV vault site alias, which I do and is correct. the only thing I can think is that the search site does not support SNI at all and this isn't going to work. We serve more than one website from this box and use SNI with certificates to do so. All other websites operate fine. Just vault will not authenticate (over http or https). 

WebHost failed to process a request.
