[gnutls-help] No supported cipher suites have been found.

Hi all,

I've been using the GnuTLS documentation to try and write my own TLS 
server.
I (think) I've loaded all the certificates properly, but on trying to 
connect (with gnutls-cli) I get "No supported cipher suites have been 
found."

I tried to use gnutls-serv which also gave the same error until I passed 
--x509certfile and --x509keyfile (which gave me errors due to my 
self-signed certificate, but that's unrelated.).

So I am wondering if my certificates aren't being loaded properly, but 
the code runs fine and it doesn't throw, so I have no idea why its not 
working.

Here is the code, only gtls_raii.cpp, gtls_raii.hpp and main.cpp are 
important.

Thanks in advance for your time.
