Duo2 to Ultimo 4k

I have changed from a Duo2 to a Ultimo 4k with exactly the same Oscam settings apart from the Oscam bin file , now I am getting freezing on sly.

Is there any magical fix for this problem.

Thanks for the help master G

I don't have an inactivitytimeout setting, what could be the cause of the bad ecm time?
