[solved] PVR headend: connection lost avery 8 seconds

So I obtained a Hauppage WinTv HVR 930C DVB C USB TV, installed the PVR TVheadend from the app store and configured it (successfully, I think) with the web interface.

Then activated Tvheadend HTSP Client over settings > addons > PVR clients and activated PVR at settings > TV.

Now every 8 Seconds a message pops up “Tvheadend HTSP Client : connection lost”.

Here are the files:

Looking forward to your ideas!

Are you sure you’ve configured the correct username:password for the server in the client?

You’re right! - Put in the data - and everything’s nice!
Thank you so much!
