SSL connection issue with custom port

[ravenz]

Our vCenter Server runs on a custom port (13443). Can connect via browser and via VI client without problems.

However, when doing: rvc 10.100.1.3:13443

I get this error:

/usr/lib/ruby/1.8/net/http.rb:586:in `connect': SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol (OpenSSL::SSL::SSLError)

Anybody? This is a very simple issue but cannot find answer anywhere.
