DVBLink stopped working after firmware upgrade

Hi,
I also have the problem that DVBLink stopped working some time ago, probably after firmware upgrade, but I'm not sure which.
Symptoms: the server is running and reports the channels to the DVBLink Windows client and Kodi17.3 clients. But I cannot tune to any channel. Also I see no EPG data.
- I have a QNAP TS-451 NAS with firmware 4.3.3.0262 and DVBLink Server 6.0.0 Build 14499 + DVBLink TVSource 6.0.0 Build 14072.
- As sources I'm using TVButler and HDHomeRun Expand with DVB-C
- DBVLink configuration was not changed in the meantime and was working before
- Server stopped and started via QNAP web GUI but no success
- Extended logs attached (can only uploaded an older zip because the current one is 450kb and the forum won't allow me to upload it)
Did QNAP change something in their latest firmware?
