Tvheadend

Hi,

I've got OScam setup and working with dvbapi, but it can only play one channel for some reason.
I found someone saying that using newcamd can solve that problem, so I tried switching to that but I cannot get it to work.

My TVHeadEnd does connect fine on the newcamd ports and I can see the connections with a tickmark in tvh, and green in oscam as expected.
But when I try playing an encrypted channel, nothing happens, the clients just hang there doing nothing, as if they were playing something with no audio or video.
I get no errors anywhere, even with debug on, and no logs in OSCam, as if tvheadend wasn't even trying to send it anything.

Here's the config :

oscam.conf

[global]
logfile                       = stdout

[cache]

[newcamd]
port                          = 9001@0500:000000,030B00,007400,007800,021110,023800;9002@0604:000000;9003@0E00:000000;9004@1010:000000;9005@1801:000000,001101,002111,007301;9006@2600:000000;9007@2602:000000;9008@2610:000000
serverip                      = 172.22.1.24
allowed                       = 172.22.1.22
key                           = 0102030405060708091011121314
keepalive                     = 1

oscam.users

[account]
user                          = tvheadend
pwd                           = tvheadend
monlevel                      = 4
group                         = 1
max_connections               = 50
cacheex                       = 1

Of course all these CAID and ident do match my reader's config exactly.
And nothing special in tvheadend, each port is configured with those settings.

And the only thing showing in the logs of OScam, not moving even when I try to play something :

2021/03/28 17:45:19 5E17B421 c   (client) encrypted newcamd:9007-client 172.22.1.22 granted (tvheadend, au=off)
2021/03/28 17:45:19 5E17B421 c  (newcamd) user tvheadend authenticated successfully (Tvheadend)
2021/03/28 17:45:19 5E17B421 c  (newcamd) AU disabled for user tvheadend

Am I missing something in the config somewhere or is this a bug ?
I would expect it to at least log some error somewhere.
