![]() So I suspect some change in Cent OS 7 to cause the problem. When devices on a network say, a browser and a web server share encryption algorithms, keys, and other details about their connection before finally agreeing to exchange data, it’s called an SSL handshake. ![]() Our server admin can see my connection attempts but also does not know the cause - apparently, all other users can connect without problems. The certificates are encrypted with MD5 and SHA1 (usercert: Signature Algorithm: sha1WithRSAEncryption CA: Signature Algorithm: md5WithRSAEncryption). (Be sure to use Tunnelblick's version of the patch on the. A fresh config.p12 (as well as fresh ca/cert/key files) did not help. We have 1 person unable to negotiate the TLS handshake, here is the situation. It used to work with the same files before and it still does work with Tunnelblick under Mac OS X. I thought the trouble may have coincided with updating to Tunnelblick 3.8.7a from 3.8.6a, which I recently did. The error occurs with the packaged versions of OpenVPN and openssl as well as with compiled OpenVPN 2.3.4/openssl-1.0.1h and OpenVPN-2.3.2/openssl-0.9.8y, either with a p12 file or ca/cert/key files. The problem appears to be related to this error: 10:05:36.666832 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) 10:05:36.667007 TLS Error: TLS handshake failed. ![]() Mon Jul 14 16:24:23 2014 us=213277 TLS Error: TLS object -> incoming plaintext read error Connection failed because of a TLS handshake error.

Workaround 2: verify CAfile (Specify a certificate in the PARM) The CAfile must be set to the CA certificate Bundle, if you set it as the server certificate, you will get the above error.
