Anycubic Vyper - Astrobox not connected

Good day
I bought Anycubic Vyper and I can’t connect via astrobox.
Until now, I have used Anycubic I3 Mega and the connection worked perfectly.
What can I do to make Vyper printer work online ???

Not sure if this printer is supported? What other controller SW does the manufacturer recommend?

I use the Vyper with Custom Firmware 6.2.1 from Rommulaner. I´ve only switch BAUD RATE to 115200. And it works perfectly.

The manufactor is Anycubic.
