Oscam webif for DM7020HD Newnigma2

Hello

I have Dreambox 7020HD and DM900UHD both originals and both with
Newnigma2 image.
Both running OSCAM but unable webif, seems that not supported.
in oscam.cfg webif is enabled. Now running on 7020 Oscam 11281
and DM900 Oscam 11360. but no webif.

Could someone link which file should be downloaded for
both receiver to enable webif function.

thanks in advance

Now both are running.

Thanks a lot
