I have the same problem , and the problem exists after compiling it with "-DFP_MAX_BITS=8192".

wolfSSL was got from github, the version is " Sep 20, 2013,  master branch  commit bdb8b9396c "

I compiled the source code on Windows 7 with VS2010.

client.exe -h vpn-students.poly.edu -p 443 -v 1

Reuslt:

err = -188, ASN no signer error to confirm failure
yassl error: SSL_connect failed
