Cable channels disappear

I am using vu solo 4k with sat&cable set up from many months and uptill last few days every thing was fine.

I have not change any thing on setting but my cable ( virmin) channels not coming on. only black screen

I have check the tuner set and it is as it was with 40973 frequency

does some one have any kind of issue?

Here is the update of my issue for every one who to think.

I am running 2x local cable cards in home PC under oscam
Then
I add 1x cs378 and 1x newcamd to my dedicated server which also got oscam

My home box(oscam) have 2 x reader 1 x conected with home pc to update cards 1 x raeder from my own Dedicated oscam.

my problem is when i try to watch cable via dedicated server while disabled the reader which conect direct to home pc then NO channels only black screen

when I conect my box oscam to home pc oscam via cccam or cs378 or newcamd it work.

can some one tell me what,s going on all of sudden as I did not change any thing at all to any server.

I have vu solo 4K which can only have oscam emu

I am using 2x omnikio reader with stand alone pc running oscam to reader card

the reason I use PC is as it can run 24/7 with out any truble while running card direct in box ( how many time we face where box crash, software freez, box reboot, restart )

Dedicated I use to share with friends as I do not like to link from Residental place.

Unless you can give me a better way to do all ?
