TLS not parsing

[klempie]

Firstly, let me say from the outset that my networks knowledge is pretty bad, more so wrt to protocols. But I've done a lot of googling and testing and I think the problem is correctly identified.

It seems to be forwarding requests correctly for http requests from the client. So calls to timeslive.co.za, ip2location.com and hulu.com return pages. But as soon as I try secure pages like netflix.com, I get ERR_RESPONSE_HEADERS_TRUNCATED.

When I go to the https access log, I get the following kind of response. There are loads of these same attempts in the space of a second or so.

Thanks in advance.
