Proxy Upgrade - http no longer works only https

[bonoboslr]

I upgraded my proxy server from 5.0.10 to 5.0.11 and now have the following problem:

2008/11/23 20:03:58 [info] 5782#0: *11326 client sent plain HTTP request to HTTPS port while reading client request headers, client: 165.146.56.105, server: zmproxy1.ourdomain, URL: "/service/soap/", host: "newmail.ourdomain"

I get 400 errors when trying to access the web interface unless I connect with https.

I just did an upgrade as well, and my settings seem OK. I don't think there's anything within the zimbra domain for this, but for the proxy & mailbox:

Here's what I have (allows 80 & 443) --- not sure these are the best settings!!

[zimbra@zproxy ~]$ zmprov -l gs zproxy.example.org | grep -i http
zimbraHttpNumThreads: 250
zimbraHttpSSLNumThreads: 50
zimbraMailMode: http
zimbraReverseProxyHttpEnabled: TRUE
zimbraReverseProxyMailMode: http
[zimbra@zproxy ~]$

[zimbra@zproxy ~]$ zmprov -l gs zproxy.example.org zimbraReverseProxyMailEnabled
# name zproxy.example.org
zimbraReverseProxyMailEnabled: TRUE
[zimbra@zproxy ~]$


#Mailbox server
[zimbra@zproxy ~]$ zmprov -l gs mbx1.example.org zimbraReverseProxyLookupTarget zimbraReverseProxyMailEnabled zimbraMailMode

# name mbx1.example.org
zimbraMailMode: http
zimbraReverseProxyLookupTarget: TRUE
zimbraReverseProxyMailEnabled: FALSE

[zimbra@zproxy ~]$
