I'm trying to set up mod_spdy with Apache (mod_spdy-0.9.4.3-r420 and apache2-2.2.22-13+deb7u3 on Debian Wheezy). As far as I can tell, everything is the way it's supposed to be, but I'm getting the "Missing NPN Extension in SSL/TLS Handshake" error from http://spdycheck.org/.
mods-enabled/ssl.load just has: (everything else is commented out)
LoadModule ssl_module /usr/lib/apache2/modules/mod_ssl_with_npn.so
and I can confirm with lsof that that is the file that apache is using right now.
Any clue why SSL isn't doing the NPN thing so that mod_spdy will work?
I have another box that seems to be configured exactly the same in this regard and it is working just fine. I'm assuming I'm missing some detail that is different :-/
