failing to connect because of SSL issue

[SodaSurfer]

Hi
I've red the issues that looks related to my problem but I'm still not able to understand how to fix it.
I'm able to find the tv device with mDNS, and I get the pairing screen of the tv on port 6467 as it should, but then after pairing with the tv, when I try to connect as I should on port 6466 I get an ssl error: SSLV3_ALERT_CERTIFICATE_UNKNOWN

and I didn't completely understand what to do based on those previous isuues related to it.

thanks
