I don't know how the mod_proxy is supposed to work and I've never tested 
it against mod_gnutls. If you run apache2ctl with -X and gdb where is 
the timeout occuring? As far as I can test when connecting to your site, 
the TLS negotiation is correctly performed and the correct certificate 
is returned.
