Hello list,
I can't fetch the page https://shop.aph.org/ using an application
that is linked against libcurl. The connection fails with
an unknown SSL protocol error.
So I tried to fetch the same page with the curl command-line tool. That
doesn't work either.
Here is what I got:

curl -k --verbose https://shop.aph.org/
* About to connect() to shop.aph.org port 443 (#0)
* Trying 205.232.169.40... connected
* Connected to shop.aph.org (205.232.169.40) port 443 (#0)
* successfully set certificate verify locations:
* CAfile: /etc/ssl/certs/ca-certificates.crt
  CApath: none
* SSLv3, TLS handshake, Client hello (1):
* Unknown SSL protocol error in connection to shop.aph.org:443
* Closing connection #0
curl: (35) Unknown SSL protocol error in connection to shop.aph.org:443

My version information is:
curl 7.19.5 (i686-pc-linux-gnu) libcurl/7.19.5 OpenSSL/0.9.8k zlib/1.2.3.3
Protocols: tftp ftp telnet dict http file https ftps
Features: IPv6 Largefile NTLM SSL libz

Thanks,
