[Nagiosplug-help] check_http

[Brian Smith]

I am getting an error on my debian servers when running check_http -v -S 
www.domain.com
the output shows
SSL seeding: OK
28133:error:140820A7:SSL routines:SSL3_CHECK_CERT_AND_ALGORITHM:missing 
export tmp rsa key:s3_clnt.c:1952:
Unable to open TCP socket
but with lynx or a web browser the page comes up and is encrypted with 
no errors.
any ideas what might be causing this or suggestions?
