I have official mono for openSUSE 12.3. The problem occurs only on Mono, Windows/.NET talks properly to the server in question:
> mono --version
Mono JIT compiler version 3.2.8 (tarball Mon Mar 10 19:23:00 UTC 2014)
> wget https://raw.github.com/mono/mono/mono-3.2.8-branch/mcs/class/Mono.Security/Test/tools/tlstest/tlstest.cs
> mcs tlstest.cs /r:System.dll /r:Mono.Security.dll
> mono tlstest.exe "https://translator.rushbase.net"
It correctly detects and prints certifcate data but ends with:
Error #-2146762486: CERT_E_CHAINING 0x800B010A
The server is properly configured as shown on https://www.ssllabs.com/ssltest/analyze.html?d=translator.rushbase.net
Heck, I even send too many CA certificates.
Also, this is not a problem with server's cipher list as the other non-SNI host with same configuration works properly on the same server: https://code2flow.com
The bug may be somehow connected to mixing SNI and this particular cipher list...
