Hargassner Internet-Gateway blocked

  • Hello,

    I have some problem with my Hargassner HV and I've seen there were similar problems, maybe someone might help me to solve mine.

    I'm trying to connect my device to the internet but when I will connect cable it's showing:

    mqtt.hargassner.at:8883 RED

    web.hargassner.at:443 GREEN

    So there is a problem with connection, also what seems strange I don't have written Smart-Webanbidung version. My device software is from 18.12.2023 SW version 2.7.2-10021626. Is it latest?

  • Hey Dude,

    First Overall: It not help if you hijack an old topic with your new Issue.

    Please open a new one of it and describe in detail your Setup.


    This Thread is about Connectivity Issues specific with Unifi Hardware.

    As summery: lots of IoT devices (include heater) don't like a switch port

    with other VLAN on it. But that is default behavior in Unifi Switches.

    So it help to set "Block ALL" on the Port.
