"scan no data, failed" with otherwise working HDHomeRun [resolved]

Added by Asko Soukka over 8 years ago

I'm new to tvandhead and cannot get my HDHomeRun to discover services.

I tried the latest release and then with the latest master from github. I have HDHomeRun Connect (hdhomerun4_dvbt) for DVB-T with the lastest firmaware.

hdhomerun_config FFFFFFFF scan /tuner0 finds channels properly

SCANNING: 546000000 (eu-bcast:30)
LOCK: t8qam64 (ss=100 snq=100 seq=100)
TSID: 0x1001
PROGRAM 17: 0 Yle TV1
...

and works properly with independent streaming apps.

Corresponding mux configuration screenshot is attached.

Yet, tvheadend fails to discover services, but just logs "scan no data, failed" over and over again.

What could I have missed and should I proceed / debug further?

Trace looks like:

Not sure what happened, but after letting hdheadend to scan the whole day, suddenly the channels started to discover.
So, fixed.

Well, a week ago I ended up resetting my tvheadend configuration, and have not been able to get successful scan ever since. HDHomeRun's own scanner still works perfectly. I was hoping it to "magically" start working againg, but not yet.

Possibly a firewall issue after all. I though, I already had proper firewall rules, because the hdhomerun CLI client worked.

This seems to work:

iptables -I INPUT 4 -s 192.168.1.5 -p udp -m state --state NEW -m udp --sport 65001 -j ACCEPT

I'm having the same issue. Plex DVR can find all the over the air channels but for some reason it can't find NBC. I've tried changing the mhz value and it doesn't help. CBS, FOX, and ABC all work fine in tvheadend, just not NBC. that iptables command doesn't work for some reason. Can you explain how a firewall issue could limit 1 channel?
