Remote no Connection

  • Titel says it.

    yesterday everything was fine. nothing was moved or touched. Kemper is in a rack and has a rackmounted Ethercon Port, so the Ethernet-Port is NEVER touched.

    Now I can't get the Remote to get Connection.
    Power check is done and then it is "Waiting for Connection". and the TAP-LED is pulsing.

    Tried 3 different Cables, also the Original one. Tried with and without the patched Ethercon-Port. Tried with and without PoE-Injector.
    LEDs of the Kemper's Ethernet Port are working/flashing.

    Is my remote broken?
    I have shows on friday and saturday. Tried to call Kemper Support (I'm in Germany) but was too late for their working hours.
    And I bought it used about 4 years ago, so I don't have a receipt and I'm afraid I won't get anything repaired because of that or have to pay a sh*tload of money...
