PVR Live TV error after restart / reboot / sleep

Hello Guys,

since 3-4 days, ive got a huge problem with live TV using the Mediaportal PVR addon.
Every time i restart, reboot or wake my HTPC up from sleep, Live TV is not working correctly.

When i try to start opening a channel after a reboot or something like that, it takes about 30 seconds to get an error message like “Media Portal PVR Client”, nothing else.
Waiting 3-5 seconds i try to start livestream again, the PVR addon restarts and everything is working fine…

I can reproduce this error everytime i restart or wake up my machine from sleep.

Here´s a log file.

The Problem occurs at 13:30:54:xxx

what i already tried… : several restarts; put a delay to TV Card; updated MP TV Server to 1.16 and back to 1.15; installed RC 2 and back to RC3; updated Kodi Plugin from Margro to xxx.137 (seems to be the newest for me)

Problem stays the same…

Thanks in advance and best regards.
