Error 400 with Canon MX925

[Praktiker]

Hi,
I tried to follow your description with the app to get the correct ipp address and I filled in all the necessary data.
Log File says: PrinterPlatformFEHLERCanon MX920 series Sensor: An error occured during getting state
13.2.2022, 14:38:59 HOOBSPrinter Platform FEHLER Received unexpected response status 400 from the printer.
ipp adress is: http://219E74000000.local./mainmenu.html
which I can access with the browser.
Would be really great if you could help me with that.
regards Praktiker.
