Axis P1425-LE dont work with EchoShow 8

[TieAge]

Hello,

I’m trying to connect my Axis camera P1425 to the Alexa Echo Show 8.
But Alexa only shows the message, the Kamara does not react.

I have changed the settings several times and deleted the device in the ALexa app and reconnected the monoce account without success.

The stream is available via ONVIF Device Manager and the account works as well.

What else has to be considered here or where is the error?
