Thank you very much!!!! your tip was very good. everything works. the problem was quite simple.
the new 4k receiver only works
oscam ...
but now comes the main reason: by the "fbc tuner" the CS server is "attacked". In my case, 4 or 8 (software) tuners were running in the background. These have summoned the transmitter.
The problem is fcc (fast chanel change). if this is activated, the CS server sends too many "requests etc.". As a result, there are many rule violations. after I disabled fcc, everything went perfect.
ALSO ... fcc at twintuner or fbc disable.
thanks again to the support. 1A !!!!!
