There's something different in your configuration. I don't see 'cwc:' lines in log (except the first login). You should see lines like:

Use '--trace descrambler,cwc'. Also it would be good to check why the non-standard ECM data are rejected in cwc_table_input(). I have no more ideas.

Oscam has no any information, except for the information of the account connection, and there is no hint. Please look at the log file.

If you use oscam from https://github.com/nx111/oscam/blob/master/module-newcamd.c#L1379 the newcamd code is not patched for DVN there.

I don't know if it's another issue or if it is related but i have big problems with a Conax card too here with latest 4.3 git version.
Sometimes it doesn't decrypt the channel and when it does it stops decrypting with 30-60 sec intervals.

With 4.2.x stable versions i have no problems.
