[NEBULA] Spotify Connect blocked by Content Filtering

Hi

Even without any category being selected, NSG is preventing me from successfully select any Spotify enabled loudspeaker from the Spotify app in order to listen music on it. Disabling Content Filtering immediately resolves the problem.

There's no information in the Event logs on the NSG. I have captured the traffic on NSG for LAN1 and WAN1, merged them in Wireshark and started with the troubleshooting. I've pulled the following HTTP hosts from the conversations and added them to the white filter on NSG which did not help:

*.edgesuite.net

*.akamaitechnologies.com

*.spotify.com

*.googleusercontent.com

Is there any possibility to debug the content filtering mechanism on the NSG? Clearly, the issue is related to that functionality. Appreciate any help.

Regards

Walter

    To All,

    The root cause is because Spotify use SSLv3 communicate with each clients, which considered is vulnerable and block by CF, if anyone who experience this issue please just leave the message here, I will help you.?

    Hello @blechkiste

    Welcome back to the community.

    May I know is there any content filtering entry in Gateway>NSS Analysis?

    Since I cannot reproduce the issue, therefore I'd like to private message you about the Org. information please be aware of your Inbox message.?

    Hi Dave

    Zyxel fixed it directly on my NSG. Reach out to Nebula_Chris. You'll probably need to open a support ticket too.

    Having the Same issue googleusercontent.com is blocked with the MSG:

    Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for doc-0o-6k-apps-viewer.googleusercontent.com. The certificate is only valid for the following names: dnsft.cloud.zyxel.com, *.dnsft.cloud.zyxel.com

    Did you try to put this domain in white list on content filtering?
