it seems that TVheadend server has problems in some situations. For example :
1. I had to re-install LibreELEC when my TV antenna was down. I did not find a solution to 'activate' the TV channels when the antenna was repaired, without re-installing THheadend server.
2. it worked fine, even for recording
3. but today it could not start any service (no list of channels, nothing) and the only solution I found was to re-install it. Desactivaye/activate did not provide anything. I re-installed TVheadend server and it is working fine now
Is there some way to "restart" TVheadend more easily in case on problems ?
Thanks for your help
