I was told to ignore the SSLv3 stuff in the log. I have options set to allow only TLS1.2 and still see SSLv3 references in the log.

Best regards,

So,  part of this appeared to be I needed a signed cert from a CA.  However,  I still have problems.

Alexa apparently requires 'Interleaved TCP on port 443 (for both RTP and RTSP). TCP socket encryption on port 443 using TLS 1.2'

How do I force Stunnel to only adhere to above?  I get the 443 part of course.  I am seeing it try SSLv3 in the log and I imagine this is wrong.

Unfortunately, without more information about what the client doesn't like about the established connection, I don't think there is anything more I can help you with :(  You *might* try playing with stunnel's cipher settings (OpenSSL options), on the off chance that the client is somewhat confused and offers for negotiation a cipher or something that it later realizes it cannot support... but that would be really weird.
