No output detected

Hi,

When TvHeadend starts up, the epg grabber can’t find any EPG. Here are my logs:

2022-03-02 00:15:18.000 [ INFO] xmltv: /usr/bin/tv_grab_wg: grab /usr/bin/tv_grab_wg
stdout
00:15:18
2022-03-02 00:15:18.002 [ INFO] spawn: Executing "/usr/bin/tv_grab_wg"

2022-03-02 00:15:18.133 [WARNING] xmltv: /usr/bin/tv_grab_wg: grab returned no data

But when I open the guide.xml file, I only see a list of channels, f.e.:

<channel id="Canvas HD">
<display-name lang="nl">Canvas HD</display-name>
<url>http://www.tvvlaanderen.be</url>
</channel>

I was looking for help on youtube, and I found this: https://youtu.be/N7GteD8-Czg?t=573
His guide.xml is alsof filled with tv shows. I don’t have that info in my guide.xml

Does anyone know whatg went wrong in my installation?
