Spotify and "Decrypt & Scan HTTPS"

Hi.

When I use Decrypt & Scan HTTPS in my firewall, spotify web site (I did not try the app) stops playing.

I cannot find a workarround how to exclude those to allow the play.

I can reach the site, I can logon, but play won't work.

The logs show all "green".

I did install the certificate in the workstation (no alerts when I use https)

Thanks,
