I suppose that there is no proxy HTTPS server in between and you have
direct communication with mod_gnutls. If this is the case could you try
if the following patch for mod_gnutls fixes the issue for you? Otherwise
could you provide debugging output of mod_gnutls (you can do that by
changing in include/mod_gnutls.h.in the MOD_GNUTLS_DEBUG definition to 1
and then run ./configure and make again).
