Squid SSL Bump TAG_NONE / HEIR_NONE

I have a transparent proxy, Squid, version 3.5.20 (latest stable at this time) I need to do domain whitelisting. Squid is configured to do SSLBumping (see squid config below)

I try to install Sumologic on a server which is located behind the squid transparent NAT.

The problem is that sumologic cannot connect out through the transparent NAT. Why can't it connect through the app, but I can using curl?

When I install Sumologic, I get the following error:

If I open a powershell and do a curl on 'service.au.sumologic.com', it works...

PS > curl https://service.au.sumologic.com

In my squid access.log I can see:

1470638115.212    164 172.26.192.122 TAG_NONE/200 0 CONNECT 54.252.91.36:443 - HIER_NONE/- -

which is service.au.sumologic.com....

Have I missed something in my squid config?

http_access deny all

The access.log line is the TCP connection arriving and being accepted to begin the bumping process.

Your ssl_bump rules say to peek at step1 then to terminate at step2 unless the client sent a TLS SNI value containing one of a few whitelisted server names in one of allowed_https_sites or NoSSLIntercept ACLs.

It seems the Java application either does not send SNI, or sends a value not whitelisted. It also crashes when TLS is unsuccessful (terminated by the other endpoint).
